DIN SF-Cu Phosphorus Deoxidized Copper Tube With Great Welding
Plus Cold Bending Properties
1. Description
The cold and hot working performance of DIN SF-Cu low phosphorus
deoxidized copper tube is very good. DIN SF-Cu low phosphorus
deoxidized copper is mainly used as busbar, conductor and parts to
be welded.
DIN SF-Cu 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.
We are willing to cooperate with you sincerely with high quality
products and sincere service, to develop the market and create
brilliance together! Our company adopts advanced online inventory
transmission system and efficient and fast logistics mode to ensure
that all customers can get accurate reply and the most stable and
safe logistics transportation in the shortest time. To ensure that
the ordered steel can be delivered in advance within the specified
period of time to meet the full customer product development task,
our company has put the expansion of company quality and service as
the future development strategic goal, each batch of die steel sold
has been inspected by relevant technical personnel and the mold
steel quality guarantee certificate issued by the company
