Inquire about JAS 2780Material overview
Cobalt alloys include multiple compositions with different service characteristics. A family name alone is not enough to identify the material required for an order.
Applications and selection
Hardfacing is one established application of cobalt-based alloys. Confirm the exact grade, substrate and operating conditions before selecting a material.
What to specify
Provide an alloy designation or approved chemistry, powder size, application process and required quantity.
Information for your inquiry
- Alloy / chemistry / specification revision
- Particle size range and units
- Morphology, flow and density requirements, if specified
- Intended process and equipment requirements
- Quantity, packaging, destination and requested date
- Required product and lot documentation
Documents and purchasing details
Identify the technical data sheet, safety data sheet and any required lot records in your request. Include packaging, destination and timing requirements so they can be reviewed with the exact material.
Grade, size, availability and documentation are confirmed with the quotation.
