ASTM C12100 Phosphorus Deoxidized Copper Tube With Great Welding Plus Cold Bending Properties
1. Description
The cold and hot working performance of C12100 low phosphorus deoxidized copper tube is very good. C12100 low phosphorus deoxidized copper is mainly used as busbar, conductor and parts to be welded.
C12100 phosphor deoxidized copper has good weldability and cold bending performance, and generally has no tendency of "hydrogen disease". It can be processed and used in reducing atmosphere, but not in oxidizing atmosphere. In Chinese standard, there are TP1 and TP2 belonged to de oxidized copper by phosphor, please see standard comparison table as below.
TP1 has less residual phosphorus than TP2, so its conductivity and thermal conductivity are higher than TP2. TP1 and TP2 are mainly used for pipe applications, and can also be supplied by plate, strip or rod, line. Used for gasoline or gas delivery pipe, drain pipe, condensation pipe, mine pipe, condenser, evaporator, heat exchanger, train box parts.
Advantages and characteristics of the company:
1. Strong price advantage; because we are the direct partner of many world famous brands in the industry, we save a lot of unnecessary expenses on the cost price of raw materials. Therefore, we have a strong price advantage, the majority of customers can buy better products in Frank at the same price!
2. Fast supply process; after the customer confirms the order and the contract comes into effect, it can generally complete the order, preparation, delivery and other work within 1-2 working days, so as to deliver the materials required by the customer as soon as possible!
