Meltolit C6

Nickel-base hard-surfacing alloy, containing diamond-like chromium borides (and carbides). Extremely resistant to wear, especially under corrosive conditions. Low coefficient-of-friction. Can be hot-formed. Finished by grinding.

Meltolit WC 60 (DURMAT A)

Special pre-alloyed tube filled with coarsely grained Fused Tungsten Carbide (FTC) for oxyacetylene welding. The FTC has an exceptionally high hardness of over 2360 HV0.1 giving outstanding wear protection to hard faced areas. For special hard facing on machine parts of unalloyed, low alloyed or cast steel with carbon content up to 0.45%. Higher carbon content could lead to cracking. Depending on the size
and composition of the area to be hard faced, the proper rod diameter and grain size should be chosen. If the area will encounter heavy abrasion a small grain size is recommended. If a cutting action is desired a larger grain size is preferable.

Meltolit WC 75 (DURMAT B)

A nickel core flexible rod coated with both fused tungsten carbide (FTC) and Ni-Cr-B-Si developed for oxyacetylene welding. The deposited alloy consists of approximately 65% FTC and 35% Ni-Cr-B-Si-matrix with a matrix hardness of 45 HRC. The overlay is highly resistant to acids, bases, lye and other corrosive media and excessive wear conditions. The rod has a low melting range of between 950 - 1050°C (1,742-1,922°F) and feature a self fluxing characteristic producing a smooth, clean welded surface.

Meltolit 110F

Flux coated Welding rod for oxy- acetylene hot welding of grey cast iron. The deposit shows the same colour and structure as grey cast iron. Mainly used to weld defects in foundries. Hardness 185 HB
after welding.

Meltolit Castiron

Welding rod for oxy- acetylene hot welding of grey cast iron. The deposit shows the same colour and structure as grey cast iron. Mainly used to weld defects in foundries. Hardness 185 HB after welding.
Used together with Meltolit GJ Flux.
