LZ632 is a highly C- Cr- Mo- Nb- W- V- alloyed open arc flux-cored wire, which forms extremely complex hard carbides. This is used for hardfacing to extremely strong abrasive mineral wear. The deposit retains its wear resistance up to 800°C. The structure consists of primarily and eutectic solidifying Cr- carbides plus Nb- Mo- W- V- carbides. The hardness reduction at a temperature of 400°C is approximately 4% and at 700°C approximately 10 %. This wire is recommended for use in sintering plants, augers and blast furnace bells, The properties are reached in only three layers and relief checking is normal.

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
