Chrome Zirconium Copper Alloys

Supplier: James Coppell Lee playlist_addCompare

Chrome Zirconium Copper (J47Z) conforming to R.W.M.A. Class 2 specifications was developed for the spot and seam welding of plated materials, such as, tin plate, terne plate, Zinc or Lead coated steels and aluminium.

Price Guide (Inc GST): POA

The unique properties of this alloy, namely its high electrical and thermal conductivity gives it a greater resistance of softening and tests have shown that J47Z retains its hardness at 500 degrees centigrade.

Chromium Zircomium Copper has the same bending qualities as Chromium Copper (J47) which allows this material to be used for the manufacture of cold formed spot welder tips.


We produce J47Z in a large range of metric and imperial rounds, squares and rectangles.

Also seam welder wheels and forgings.
