Main features

Application examples

T2

It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed. Containing less impurities that reduce electrical and thermal conductivity, trace oxygen has little effect on electrical conductivity, thermal conductivity and processing performance, but it is easy to cause "hydrogen disease", and it is not easy to process (anneal) in a reducing atmosphere at high temperatures (such as >370°C) , Welding, etc.) and use.

Used for electrical, thermal, and corrosion resistant equipment. Such as: wire, cable, conductive screw, detonator for blasting, evaporator for chemical industry, storage and various pipelines, etc.

TU1、TU2

High purity, excellent electrical and thermal conductivity, no "hydrogen disease" or very little "hydrogen disease", good processing performance, welding, corrosion resistance and cold resistance

Mainly used for various hardware products, lamps, pipe fittings, zippers, plaques, rivets, springs, sedimentation filters, etc. of electric vacuum instrumentation devices

TP1

It has good welding performance and cold bending performance. It is generally prone to "hydrogen disease". It can be processed and used in a reducing atmosphere, but it is not suitable for processing and use in an oxidizing atmosphere. TP1 has less residual phosphorus than TP2, so its power loss and thermal conductivity are higher than TP2

Mainly used in pipe applications, but also can be supplied in plates, strips, rods, and wires. Used as gasoline or gas delivery pipe, drain pipe, condenser pipe, mine tube, condenser, evaporator, heat exchanger, train car parts
