Copper
Product name | Copper |
| Product category | Purple Brass |
| Chemical composition | CuAg:≥99.99 Sn :≤0.002 Zn:≤0.005 Pb:≤0.005 Ni:≤0.005 Fe:≤0.005 Sb :≤0.002 S :≤0.005 As :≤0.002 Bi:≤0.001 O:≤0.06 （Impurity）Note:≤0.1 |
| Mechanical properties | Tensile strength (o b (MPA): more than or equal to 205: elongation (10%): equal to or larger than 30%: Note: Strip Tensile Properties at room temperature of specimen size: thickness is more than or equal to 0.3 |
Heat treatment specification | Heat treatment temperature of 900 ~ 1050, 500 ~ 700 of the annealing temperature, cold hardening copper and then cold hardening of the copper in the reheating temperature ~ ~ 300 ~ 200. |
| Product description | A series of copper copper belt, because the name is red. It doesn't have to be a pure copper, sometimes also added a small amount of deoxidizing elements or other elements, to improve the quality and performance and also was included into the copper alloy. |
Product performance | Copper electrical conductivity and thermal conductivity after silver, widely used in the production of conductive, heat transfer equipment. Copper in the atmosphere, seawater and some non oxidative acid (hydrochloric acid, sulfuric acid, alkali, salt solution and various organic acids (acetic acid, citric acid), good corrosion resistance for the chemical industry. In addition, copper has good weldability, can be cold, thermoplastic processing into various semi-finished products and finished products. |
