Hot sale tungsten Copper alloy bar W80Cu20

RWMA CLASS	RWMA NO.	RWMA GENERAL USE	RWMA DESCRIPTION
10 copper tungsten	C74450	Flash and butt welding electrodes where good electrical and thermal conductivity is necessary and where a degree of malleability is desired.	A powder metallurgical combination of 45% copper and 55% of the refractory metal tungsten. Not a true alloy. This combination produces dense, hard metals of superior wear resistance and strength at elevated temperatures. In addition, they possess good thermal and electrical conductivity.
11 copper tungsten	C74400	Projection welding electrodes, flash and butt welding electrodes, light upsetting and seam welding bushings. Harder than Class 10 and used where moderate pressure is required. This material can also be used for spot welding low conductivity steels such as stainless.	A powder metallurgical combination of 25% copper and 75% of the refractory metal tungsten. Not a true alloy. This combination produces dense, hard metals of superior wear resistance and strength at elevated temperatures. In addition, They possess good thermal and electrical conductivity.
12 copper tungsten	C74350	Heavy duty projection welding electrodes, electro-forming and electo-forging electrodes facings for upsetting of studs and rivets, cross wire welding of large diameter wire and rod.	A powder metallurgical combination of 20% copper and 80% of the refractory metal tungsten. Not a true alloy. This combination produces dense, hard metals of superior wear resistance and strength at elevated temperatures. In addition, they possess good thermal and electrical conductivity.
