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 | It is a versatile Brass material suitable for decorative hardware, stamped bent parts, small ordinary mechanical parts, connectors, panels, nameplates, instrument parts, and medium- to low-strength copper alloy parts. |
|---|---|
| Precision performance | Brass H62 suitable for CNC machining, stamping, bending, drawing, drilling, tapping, and general precision hardware processing. Compared toPure Copper, H62 offers better processing stability; Compared to HPb59-1, H62 has slightly lower cutting efficiency, but generally offers better formability and environmental compatibility. Actual accuracy is affected by part dimensions, plate thickness, material condition, cutting tools, molds, clamping methods, machining paths, and post-processing methods. |
| Dimensional tolerances | Conventional dimensional tolerances for CNC machining Brass H62 can be referenced ± 0.02mm to ±0.10mm, while ordinary structural parts and turned parts can be evaluated at ±0.05mm to ±0.20mm. The overall dimensional tolerances for stamped, bended, and large-sized thin plates may be larger; generally, the reference ± 0.10mm to ±0.50mm is recommended. These values are standard reference ranges and are not absolute guaranteed tolerances for all structures. Precision shaft diameter, threads, hole positions, and mating surfaces should be separately marked with tolerance requirements. |
| Minimum Wall Thickness | The wall thickness of ordinary CNC machined structures is recommended to be no less than 0.8mm-1.0mm. Stamped, bent, and decorative pieces can use thinner sheets depending on the material condition and structure, but it is not recommended to design them too thin at load-bearing points. Threaded connections, pressed parts, thin-walled sleeves, and assembly stress points should be appropriately thickened to avoid processing deformation, compression cracking, or insufficient assembly strength. |
| Recommended wall thickness | Standard decorative pieces, nameplates, and stamped parts are recommended to be 0.5mm-1.5mm; ordinary small Brass structural parts are recommended to be 1.0mm-2.0mm or more; nuts, joints, sleeves, decorative parts, and threaded hole positions should be appropriately thickened according to thread specifications, assembly strength, and force requirements. Bending parts should be reasonably thickened based on plate thickness, bending radius, and material condition. |
| Minimum aperture | CNC drilling can achieve smaller hole diameters, but deep small holes still require consideration of chip evacuation, burrs, and tool strength. For general designs, the recommended aperture is no less than 0.8mm-1.0mm. Stamping or etching holes are recommended to have a diameter no less than 1 times the plate thickness, and stabilization design should be no less than 1.0mm. Deep holes, small threaded holes, blind holes, and precision fit holes should be evaluated based on machining methods, burr control, and post-processing requirements. |
| Assembly clearance | For precision metal assembly, 0.02mm-0.10mm per side can be reserved according to fitting requirements; for ordinary plug-ins, shaft hole fits, and hardware assembly, it is recommended to reserve 0.10mm-0.30mm per side. If subsequent nickel, chrome, tin, gold, or oxidation treatments are needed, additional gaps should be reserved according to the thickness of the coating. Stamped bent parts must also consider springback and plate thickness tolerances to avoid overtightening or surface scratches. |
| Detailed performance | Brass H62 suitable for processing threads, chamfers, steps, holes, grooves, decorative textures, stamped markings, brushed surfaces, and small hardware details. After stamping, etching, and CNC machining, the details are rendered well, making them suitable for creating decorative structures with a metallic texture. Small text, logos, and markings are recommended to be marked by laser marking, engraving, etching, embossing, silkscreen printing, or electroplating for marking. |
| Surface effect | Brass H62 original surface usually appears as a golden yellow or light Brass metallic texture. Polishing produces a brighter Brass appearance, brushing produces a delicate linear metallic texture, and sandblasting produces a matte Brass effect. Long-term exposure to air, humidity, or sweat environments may oxidize and darken, resulting in dark yellow, brown, or spots on the surface. If long-term appearance is needed, nickel, chrome, gold, transparent protection, or oxidation resistance treatments can be applied. |
Based on material characteristics and suitable product ranges, customer needs are broken down into easier application directions to determine.

It is a versatile Brass material suitable for decorative hardware, stamped bent parts, small ordinary mechanical parts, connectors, panels, nameplates, instrument parts, and medium- to low-strength copper alloy parts.
The main features of Brass H62 are good formability and decorative properties, making it suitable for stamping, bending, drawing, polishing, brushing, and conventional machining. Its color is golden yellow or light Brass, and its appearance is more stable than H59, making it suitable for making decorative panels, hardware parts, and parts that require a certain texture. H62 is lead-free or usually contains less lead, making it more suitable than HPb59-1 for scenarios where lead-containing easy-cutting Brass is not desired, but its machining efficiency is not as good as HPb59-1.
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 H62.
Post-processing of Brass H62 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 H62 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 cutting efficiency and automatic lathe machining performance are required, HPb59-1 lead Brass can be chosen; If lower cost and standard Brass structural parts are needed, H59Brass can be chosen; If higher electrical and thermal conductivity is required, Pure CopperT2 or TU2 Oxygen-Free Copper can be chosen; If higher elasticity and fatigue life are needed, beryllium copper C17200 or phosphor bronze can be chosen; If better corrosion resistance and structural strength are required, 304 stainless steel, 316 stainless steel, or QAl9-4 Aluminum Bronze can be chosen.
If customers mainly care about Brass appearance, stamping and bending performance, ordinary hardware structure, and good decorative effects, Brass H62 is a more suitable choice. If customers mainly handle batch turning of nuts, joints, and automatic lathe parts, the HPb59-1 offers higher processing efficiency; If customers care about electrical and thermal conductivity, they should choosePure Copperor oxygen-free copper; If the customer's products involve food, drinking water, children's products, or export environmental protection requirements, material standards and regulatory requirements should be confirmed in advance.
