C2680, C6280, C2600, C2801, C2200, C2680 - Are these imported copper or domestic production? And why are they marked with the national standard number: C2680 Standard: GB/T...?

The difference between brass and phosphor bronze, C5191 phosphor bronze sheet, C2680 brass strip

C5191 Tin Bronze Plate contains 5-8% tin. Composed of iron, zinc, and other trace elements, it offers excellent ductility and fatigue resistance. Suitable for electrical and mechanical materials, it boasts higher reliability than common copper alloys. Mechanical properties: Ultimate tensile strength σb (MPa): ≥ 635; Elongation δ5 (%): ≥ 10; Hardness: ≥ 190. Lower wear resistance than C5191.

2. Is C2680 imported copper material or domestic? Why is it a national standard grade: C2680 Standard: GB/T...

The material number corresponding to C2680 in our country is H65. Japanese copper alloy brands: C1020, C1100, C1201, C1220, C1221, C2100, C2200, C2300, C2400, C2600, /11. C3713, C4250, C4430, C4621, C4640, C6140, C6161, C6280, C6301.

3. What does C2680R1/2H1/2H for copper alloy mean?

C2680R1/2H is a Japanese standard brass strip, with "1/2H" indicating a semi-hard material condition. As shown in the following image: C2680R1/2H brass boasts excellent mechanical properties, high strength and plasticity, and can withstand both cold and hot pressure processing and corrosion. This brass is used for making hardware, household goods, screws, and other products.

Why is the color of the C2680 brass material different?

1. The surface forms a CuO protective layer; 2. This is dirt. Wipe with a polish to see if it's copper rust or old treatment; 3. Please attach photos. One is the manufacturing process. Another is that the material is fake, and another is that the surface has been oxidized. C2680 is brass, which is prone to oxidation in the air over time, causing uneven surface colors. C2680 is a Japanese standard brass strip, complying with standard: JISH31002006. C2680 brass has good mechanical properties, high strength and plasticity, and can withstand cold and hot pressure processing well, with tendencies towards corrosion and cracking.

What is the material of C2680P-1/2H?
