What is Cobalt Base Alloys ERCoCr-A Filler Wire?

Cobalt Base Alloys ERCoCr-A Filler Wire is made up of Cobalt (balance), Chromium 2832, Tungsten 4.5 6.5, Nickel 3, Carbon 2.33, Silicon 2, and Iron 3. This is an alloy that is characterized by excellent hardness, corrosion and wear resistance particularly at high temperatures. It provides a hardness of about 40 -45 HRC and has strength and toughness even in extreme thermal and mechanical stress. ERCoCr-A is most commonly used in hardfacing components that are subjected to abrasion, erosion and heat generating services, so that they will have a long life and reliable services in harsh conditions.

Cobalt Base Alloys ERCoCr-A Filler Wire Uses

Cobalt Base Alloys ERCoCr-A Filler Wire is common in hardfacing and overlaying demanding the best wear, corrosion and heat resistance. It is also perfect in valve seats, cutting tools, turbine blades, pump sleeves, bearing surfaces and engine parts working in high friction or high temperatures. It is generally used in the aerospace, petrochemical, power generation and mining industries, to obtain long life of parts subject to abrasion, erosion, and oxidation. ERCoCr-A is hard and stable to 870 o C and therefore a good fit in restoring the worn out parts and guarding the new surfaces in the areas of critical industrial processes.
