Civen Metal Material (Shanghai) Co., Ltd. is one of the leading manufacturers and suppliers of rolled brass foil in China. Welcome to buy bulk durable rolled brass foil made in China here from our factory. If you have any enquiry about cooperation, please feel free to email us.
Rolled brass foil is a copper-zinc alloy supplied in thin, flat form for applications that require a balance of surface appearance, wear resistance and mechanical strength. Its properties vary with the material temper, making temper selection an important part of matching the foil to the intended forming and service conditions.
CIVEN Metal offers rolled brass foil in thicknesses from 0.01 to 0.15 mm and widths from 4 to 200 mm. Available tempers include O, 1/4H, 1/2H and H. Buyers can use the technical data below to compare dimensional requirements, mechanical properties and physical characteristics before specifying the material for a component or production process.
Rolled Brass Foil: Material Characteristics
Brass is an alloy of copper and zinc. Compared with pure copper, its mechanical properties can be adjusted through alloy composition and material temper. Rolled brass foil is used in applications where surface finish, hardness, wear resistance and forming behavior all matter.
CIVEN Metal rolled brass foil has a flat sheet form and a consistent surface finish. The annealing process can be used to adjust the material between softer and harder conditions, helping buyers select a temper suited to the requirements of the finished component.
For applications requiring more precise dimensional control, compare the material requirements with High-Precision RA Brass Foil before finalizing the specification.

Physical Properties
The physical properties listed for this rolled brass foil are shown below. These values provide a reference for preliminary material selection and engineering evaluation.
| Property | Value |
|---|---|
| Density | 8.5 g/cm³ |
| Electrical conductivity at 20°C | 27% IACS |
| Thermal conductivity at 20°C | 120 W/(m·°C) |
| Elastic modulus | 105,000 N/mm² |
| Coefficient of thermal expansion, 20–300°C | 20 × 10⁻⁶ °C⁻¹ |
Mechanical Properties by Temper
The temper affects the balance between strength, elongation and hardness. Use the following values to compare the listed conditions when selecting material for forming or component manufacturing.
| Temper | JIS Temper | Tensile Strength (Rm, N/mm²) | Elongation (A50, %) | Hardness (HV) |
|---|---|---|---|---|
| M | O | 350–410 | ≥25 | 80–120 |
| Y4 | 1/4H | 375–445 | ≥15 | 105–145 |
| Y2 | 1/2H | 385–460 | ≥12 | 120–165 |
| Y | H | 450–510 | ≥5 | 135–185 |
The listed values show a change in mechanical behavior across the available tempers. Softer conditions provide greater elongation, while harder conditions offer higher tensile strength. The appropriate selection depends on the forming method, component geometry and required mechanical performance.
Other property combinations may be available upon request, subject to technical confirmation.
Applications of Rolled Brass Foil
Rolled brass foil can be considered for applications that benefit from its golden appearance, wear resistance and adjustable mechanical properties. The current product information identifies the following application areas:
• Decorative components: where the appearance of the brass surface is part of the finished product.
• Protective and reinforcing parts: where hardness and resistance to impact are relevant.
• Gaskets: where wear resistance is an important material consideration.
• Electrical heating components: where the electrical resistance of brass is relevant to the design.
• Radiator and machinery-related components: including automotive, agricultural machinery, mining machinery, engineering machinery, diesel locomotive, shipbuilding and generator applications identified in the current product information.
Actual suitability depends on the component design, operating conditions, forming process and required material properties. Buyers should confirm the grade, temper and dimensions against the intended application before production.

The listed references have different scopes. Confirm the relevant standard and edition for the intended application rather than assuming that every listed reference applies to every supplied specification.
Selecting Rolled Brass Foil for Your Application
When evaluating rolled brass foil for a new component or an existing production process, define the key requirements before requesting a quotation:
When selecting a material for a specific application, the alloy composition and required properties should be considered together. Where the application requires a copper-based material rather than a copper-zinc alloy, compare the requirements with RA Copper Foil as an alternative.
• Thickness and width: Confirm the required dimensions and tolerances.
• Temper: Select O, 1/4H, 1/2H or H according to the required balance of strength and elongation.
• Mechanical properties: Check tensile strength, elongation and hardness against the forming process and finished component.
• Physical properties: Consider electrical and thermal conductivity where they affect the application.
• End use: Describe the component, operating environment and downstream processing method.
Providing these details helps the technical team assess whether the listed rolled brass foil specification is suitable or whether a different material condition should be considered.
