RA Copper Foils
CIVEN Metal supplies rolled annealed (RA) copper foils and related copper-alloy foils for applications where controlled thickness, surface characteristics, electrical conductivity, mechanical performance, or formability are important.
The RA Copper Foils range covers standard, high-precision and treated copper foils, together with RA brass and RA bronze foils for more specialized material requirements. Select the material according to the application, required foil properties, dimensions, and processing conditions.
RA Copper Foil Types
Standard RA Copper Foil
Standard RA copper foil is intended for applications that require the characteristic properties of rolled annealed copper foil and controlled material dimensions. It provides a general material option for customers evaluating copper foil for electrical, electronic, and industrial applications.
High-Precision RA Copper Foil
High-Precision RA Copper Foil is designed for applications where tighter dimensional control and consistent material characteristics are important. It is a suitable option when the foil needs to meet more demanding requirements for precision processing and component production.
Treated RA Copper Foil
Treated RA Copper Foil is available for applications where the surface condition of the foil is an important part of the material selection. Treatment options can be considered according to the customer's downstream process and application requirements.
RA Brass Foil
RA brass foil combines the characteristics of rolled annealed processing with a copper-zinc alloy composition. CIVEN's RA brass range includes options developed for electronics, electrical components, stamping, shielding, and applications requiring a balance of conductivity, strength, formability, or dimensional stability.
RA Bronze Foil
RA bronze foil uses a copper-tin alloy and is available in different grades and performance profiles. Current product options include high-conductivity, wear-resistant, spring-grade, high-strength, thin, and high-precision RA bronze foils.

Applications of RA Copper and Copper-Alloy Foils
RA foils are selected across different industrial applications depending on the required material properties and downstream processing method.
Typical application areas represented by the current product range include:
• Electronic components
• Electrical connectors
• Precision stamping
• Electromagnetic shielding
• Spring components
• Applications requiring repeated bending or fatigue resistance
• Applications requiring dimensional stability
• Industrial components requiring specific copper-alloy properties
For a specific application, material selection should consider the required alloy, foil thickness, width, mechanical properties, surface condition, and processing requirements.
How to Select the Right RA Foil
The right RA foil depends on more than the material name. Before requesting a quotation, buyers should normally define the following requirements:
Material:
Specify whether the application requires copper, brass, or bronze foil.
Precision requirements:
For components with tighter dimensional requirements, a high-precision RA foil may be more appropriate than a standard material.
Mechanical requirements:
Strength, flexibility, bending performance, fatigue resistance, and formability can affect the choice between different RA foil grades.
Surface requirements:
If surface characteristics or treatment are important to the downstream process, specify the required surface condition when requesting a quotation.
Application and processing:
Tell us how the foil will be processed, such as stamping, forming, electronic component manufacturing, shielding, or other downstream operations.
Providing these details allows the material and product configuration to be evaluated against the actual application rather than selecting a foil only by thickness or alloy name.

FAQ
Q: What is RA copper foil?
A: RA copper foil is copper foil produced through a rolled and annealed manufacturing process. It is used when the required application calls for specific combinations of conductivity, mechanical properties, formability, dimensional control, or surface characteristics.
Q: What is the difference between RA copper foil and RA brass foil?
A: RA copper foil and RA brass foil use different base alloys. RA brass foil is a copper-zinc alloy, while RA copper foil is based on copper. The appropriate choice depends on the electrical, mechanical, forming, and application requirements of the finished component.
Q: When should I choose high-precision RA copper foil?
A: High-precision RA copper foil can be considered when tighter dimensional control and more consistent material characteristics are important to the downstream manufacturing process.
Q: What RA bronze foil options are available?
A: The current RA bronze range includes high-conductivity, wear-resistant, spring-grade, high-strength, thin, and high-precision options. The appropriate grade depends on the mechanical, electrical, dimensional, and processing requirements of the application.
Q: What information should I provide when requesting an RA foil quotation?
A: Please provide the required material or alloy, thickness, width, application, downstream processing method, surface requirements, and any specific mechanical or dimensional requirements you already have. This gives the technical team enough information to identify the appropriate product range.
