Welding materials are available in atomized metal powder (standard and precise grades for use with precision function), sheet metal (0.1-0.2mm thick) and wire (0.2-0.6mm dia. and 0.015-0.025" dia.). The welding materials are particularly suitable for use with rolled, prehardened, quenched and tempered, free cutting steels and stainless steels. Each has a different hardness and metal mold application.

Ideally, weld material hardness should match base metal hardness. As a rule, however, very good results can be achieved with N80 powder or NAK80, NTA1 or NTA2 sheet (supplied with Weldmax). These produce strong homogeneous welds on most molds.

Molds for small parts usually made of harder alloys should be welded with N51 powder (supplied with Weldmax) or harder sheet material.
