Cobalt Base Alloys

Corolit 1
MF 20-55-CGTZ

Corolit 1 deposits a cobalt-base alloy with an austenitic-ledeburitic structure. This is the hardest of the standard cobalt-base alloys. It has a high resistance to corrosion (especially to reducing acids and impact), extreme wear and temperature shocks. The alloy is only machinable by grinding. Best used on wear pads, rotary seal rings, pump sleeves and centerless grinder work rests.

Corolit 6 MF 20-45-CTZ
Corolit 6 LC MF 20-40-CTZ
Corolit 6 HC MF 20-45-CTZ

Cobalt-base alloys with an austenitic-ledeburitic structure containing chrome and tungsten carbides. These alloys are resistant against high corrosion and abrasion, high impact stress and extreme temperature shocks. The deposit is machinable by hard metal tools. Best used on steam and chemical valves and on equipment handling hot steel, such as tong bits, hot steel-shear blades, etc.

 

Corolit 21
MF 20-350-CKTZ

Cobalt-base alloy with high resistance against abrasion, temperature shocks and corrosion. This alloy is suitable for hardfacing cutting edges of long knives and other tools used in the wood, plastic, paper, carpet and chemical industries.

Corolit 12
MF 20-50-CTZ

This cobalt base-alloy is the toughest, with highest corrosion and thermal resistance of all cobalt-base alloys. The weld deposit is machinable and is used on components that are exposed to high temperatures, corrosion and impact stress, such as valve seats as well as components in the chemical industry. Work hardening up to 45 HRc.
