LZ642 is a highly C- Cr- Mo- W- V alloyed open arc or gas shielded arc flux-cored wire, deposit metal is a very hard martensitic micro structure with carbides, resistant to strong mineral abrasion also at higher temperatures. Compared to LZ643, this wire contains higher alloy carbide, higher wear and temperature resistance under mild impact working condition.

LZ643 is a highly C- Cr- Mo- W- Nb alloyed open arc or gas shielded arc flux-cored wire that deposits a very hard martensitic micro structure with carbides. The deposit is resistant to strong mineral abrasion also at higher temperatures. It has good result on hardfacing sinter parts

LZ650 is open arc flux cored wire, deposit metal is martensitic chromium carbide alloy, hardness can reach to 63HRC at single layer, weld metal thickness should be limited in 4mm.
