Brass is a type of copper alloy sheet metal part made from Brass sheet metal through laser cutting, CNC punching, bending, stamping, drawing, and anti-oxidation processes. Brass has good metal decorative properties, formability, corrosion resistance, electrical conductivity, and medium strength, and is commonly used in decorative panels, nameplates, connectors, terminal pieces, hardware parts, instrument panels, process parts, and small functional structural components. Compared toPure Copper, Brass has better strength and hardness; Compared to stainless steel, Brass has a more golden color and stronger decorative appeal, but its corrosion resistance and strength are generally not as good as stainless steel.
By focusing on application scenarios, boundaries of advantages, and non-recommended scenarios, it helps sales, customer service, and quoting staff quickly determine whether the material meets current part requirements.
Golden metal has a good texture, strong decorative properties, good forming performance, good bending and stamping performance, strength higher thanPure Copper, corrosion resistance better than ordinary carbon steel, can be polished, brushed, and electroplated, suitable for small hardware and exterior sheet metal parts.

The following parameters come from product information and material knowledge fields, used for design review, quotation communication, and preliminary judgment before material selection.
| Material positioning | Suitable for making decorative panels, nameplates, connecting pieces, terminal plates, hardware parts, instrument surface panels, light-duty structural parts, craft decorative parts, and sheet metal parts requiring a golden metallic texture. |
|---|---|
| Precision performance | Brass sheet metal is suitable for laser cutting, CNC punching, bending, stamping, and general machining. The cutting profile and hole position accuracy are relatively good, but the overall bent dimensions are affected by plate thickness, bending radius, material condition, bend springback, and surface treatment. Brass is easier to maintain shape thanPure Copper, but thin panels and large panels may still warp, deform, or scratch. Appearance parts and assemblies should be individually controlled for size and surface quality. |
| Dimensional tolerances | For standard laser cutting, dimensional tolerances can be referenced ± 0.10mm to ±0.30mm, and after bending and forming, the overall dimensional tolerance can be referenced ± 0.30mm to ±1.00mm. Small connectors, nameplates, and simple bent parts are usually easier to control, while large panels, multi-bent parts, stretched parts, and plated parts may show greater deviation. These values are standard reference ranges and are not absolute guaranteed tolerances for all structures. Assembly holes, appearance edges, and key bending dimensions should be separately marked with tolerance requirements. |
| Minimum Wall Thickness | Brass sheet metal is usually selected based on plate thickness, with common thicknesses including 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm, and so on. Ordinary decorative panels and nameplates can use thinner panels; It is recommended that ordinary connectors, panels, and small structural components be no less than 0.5mm-1.0mm; areas requiring screw fixing, riveting, or bearing assembly forces should be appropriately thickened. |
| Recommended wall thickness | Standard decorative panels, nameplates, and panels are recommended 0.5mm-1.5mm; connectors, terminal plates, brackets, and ordinary hardware structural parts are recommended 1.0mm-2.0mm; positions requiring screw tightening, riveting, bending load-bearing or flatness maintenance are recommended 1.5mm-3.0mm, and rigidity is improved through folding, flanging, reinforcing ribs, or local thickening. |
| Minimum aperture | For laser cutting or CNC punching, the hole diameter should be no less than one of the plate thickness, and for stable design, the hole diameter should be no less than 0.8mm-1.0mm. Small holes, dense holes, and holes near the bending line are prone to burrs, deformation, or edge strains. Screw holes, positioning holes, riveting holes, and assembly holes should be reasonably allowable according to board thickness, fastener specifications, plating thickness, and assembly requirements. |
| Assembly clearance | For ordinary sheet metal assembly, it is recommended to reserve 0.10mm-0.30mm on one side; for inserts, slots, multiple bending, and electroplated parts, it is recommended to appropriately increase the gap according to plate thickness, bending error, and coating thickness. If subsequent coating is required for nickel, chrome, gold, transparent protection, or spraying, additional consideration of surface treatment thickness should be taken into account to avoid over-tight assembly, surface scratches, or interference with hole positions. |
| Detailed performance | Brass sheet metal is suitable for making holes, grooves, folded edges, flanges, shallow reliefs, nameplate text, decorative textures, connector contours, and small hardware details. Small text, logos, and markings can be achieved through etching, laser marking, engraving, stamping, screen printing, or etching coloring. Small sharp corners, narrow bridges, tiny holes, and thin edges can easily cause burrs, deformation, or uneven surface treatment. It is recommended to enlarge the appearance details appropriately. |
| Surface effect | Brass original surface usually has a golden or light golden-yellow metallic texture, with a distinct decorative effect. Polishing produces a glossy Brass appearance; brushing produces a delicate linear metal texture; sandblasting produces a matte Brass effect; nickel, chrome, or gold plating produces different metallic color finishes. Long-term exposure to air, humidity, sweat, or oil stains may cause the surface to gradually darken, brown, or develop oxidation spots. |
Based on material characteristics and suitable product ranges, customer needs are broken down into easier application directions to determine.

Sheet Metal Fabrication Brass combines certain mechanical strength with good decorative appearance, appearing in golden or light gold colors, suitable for making visible panels, decorative parts, and ordinary hardware. Brass is harder thanPure Copperand maintains its shape better after bending and stamping, but its electrical and thermal conductivity is not as good asPure Copperor oxygen-free copper. Brass long-term exposure to air, humidity, or sweat environments will oxidize and darken, requiring anti-oxidation, electroplating, or transparent protection treatment according to appearance requirements.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for Brass.
Post-processing of Brass affects appearance, dimensions, hole position, assembly clearance, and usage validation results, and should be explained in advance during quotation, DFM review, and sample confirmation stages.
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining, coating, and trial assembly allowances.
For common issues such as threads, snaps, strength, temperature resistance, and weather resistance, identify in advance whether the material needs to be replaced or if another processing method should be used.
When customer demand exceeds Brass material boundaries, it is necessary to combine strength, temperature resistance, toughness, long-term stability, and mass production goals to promptly recommend alternative materials or processing technologies.
If higher electrical and thermal conductivity is required, Pure CopperT2 or TU2 Oxygen-Free Copper can be chosen; If higher corrosion resistance and long-term appearance stability are required,304 Stainless Steel or 316 can be chosen; If lower-cost housing components are needed, SPCC, SECC, or Q235 powder coating parts can be chosen; If lightweight is needed, AL5052 aluminum alloy sheet metal can be chosen; If higher elasticity and fatigue life are required, beryllium copper, phosphor bronze, 65Mn, or 301 stainless steel can be chosen.
If customers mainly care about the appearance of golden metal, decorative effects, ordinary hardware functions, and medium- to low-strength sheet metal structures, Brass sheet metal is a more suitable choice. If customers require high current conductivity, strong heat dissipation, or high conductivity connections, Pure Copperor oxygen-free copper should be prioritized; If customers need to use it long-term outdoors, in humid, salt spray, or highly corrosive environments, they should choose stainless steel, surface-plated Brass parts or add reliable protective coatings.
