C26000 Yellow Brass Sheet, also known as C260 Cartridge Brass or 70/30 Brass, is a copper-zinc alloy containing approximately 70% copper and 30% zinc. It combines excellent cold formability, good corrosion resistance, and a characteristic golden-yellow appearance. Typical applications include electrical terminals, stamped components, decorative hardware, and precision sheet metal parts.
C26000 can be bent, stamped, punched, and deep-drawn into complex shapes. Soft annealed tempers are preferred for demanding forming operations, while harder tempers provide greater strength and stiffness. The alloy also has good solderability and accepts polished, brushed, or plated finishes. Compared with C11000 pure copper, C26000 has higher strength but lower electrical and thermal conductivity. Selecting the appropriate temper helps control springback and reduce cracking during fabrication.
Sky Steel Group supplies C26000 yellow brass sheets for electrical component manufacturers, metal fabricators, and industrial distributors. Standard and custom dimensions are available, with cut-to-size processing based on customer drawings. Buyers can specify the required thickness, width, length, temper, and order quantity when requesting a quotation.

C26000 Yellow Brass Sheet Applications
Hardware & Industrial Components
C26000 yellow brass sheets are used to manufacture brackets, fittings, fastener components, and industrial hardware. Their mechanical strength, corrosion resistance, and cold formability suit fabricated parts for machinery, furniture fittings, and general equipment assemblies. Depending on the component design, sheets can be punched, bent, or stamped into finished shapes.
Stamping & Deep Drawing
C26000 brass sheets are commonly specified for stamped parts, deep-drawn shells, housings, and precision-formed components. Soft annealed tempers provide the ductility needed for complex shapes and multiple forming stages. Half-hard tempers offer greater stiffness but require consideration of bend radius, springback, and cracking during fabrication.
Architectural & Decorative Applications
C26000 yellow brass sheets are used for interior wall panels, decorative trim, door fittings, and architectural metalwork. Their golden-yellow color can be enhanced through polishing, brushing, or protective coatings. For exposed surfaces, finish selection should account for oxidation, tarnishing, and maintenance requirements over time.
Electrical & Electronic Components
C26000 brass sheets are fabricated into electrical terminals, connector parts, contact supports, and stamped electronic components. The alloy combines moderate electrical conductivity with good mechanical strength and formability. It is generally selected for components requiring secure mechanical connections rather than the maximum conductivity associated with pure copper grades.
Frequently Asked Questions About C26000 Yellow Brass Sheet (C260 Cartridge Brass)
1. What is C26000 yellow brass sheet?
C26000, also known as C260 Cartridge Brass or 70/30 Brass, is a copper-zinc alloy containing approximately 70% copper and 30% zinc. It has excellent cold formability, good corrosion resistance, and a characteristic golden-yellow appearance. Typical applications include stamped components, deep-drawn parts, electrical terminals, and decorative hardware.
2. What is the difference between C26000 and C11000 copper?
C26000 is a copper-zinc alloy, while C11000 is Electrolytic Tough Pitch (ETP) copper containing at least 99.90% copper. C26000 generally provides higher strength and hardness in comparable tempers, along with good cold-forming properties. C11000 has significantly higher electrical and thermal conductivity and is preferred for busbars and high-current electrical components.
3. Can C26000 brass sheet be stamped, bent, or deep drawn?
Yes. C26000 is suitable for stamping, bending, punching, and deep drawing. Soft annealed (O60) material is preferred for complex forming operations, while half-hard (H02) provides greater strength and stiffness. Bend radius and springback should be considered when selecting the temper, particularly for precision-formed components.
4. What are the main applications of C26000 yellow brass sheet?
Typical applications include industrial hardware, brackets, fittings, stamped electrical terminals, connector parts, deep-drawn housings, decorative wall panels, and architectural trim. The appropriate temper and surface finish depend on the forming process and final operating conditions.
5. What thicknesses and sizes are available for C26000 brass sheet?
Sky Steel Group supplies C26000 yellow brass sheets in standard and custom dimensions. Cut-to-size processing is available according to customer drawings. Please specify the required thickness, width, length, temper, surface finish, and order quantity when requesting a quotation.
6. What standards and certificates are available for C26000 brass sheet?
C26000 brass sheet is commonly specified to ASTM B36/B36M. Mill Test Certificates (MTC) can be requested with the order. If EN 10204 3.1 inspection certificates or specific chemical composition and mechanical test reports are required, please confirm these requirements before production.
