Heavy Tungsten Alloy Products
Heavy tungsten alloy supply
Heavy tungsten alloys are normally specified by alloy system, tungsten content, density and required properties. ASTM B777 establishes four classes of machinable tungsten-base high-density metal. A purchase request should identify the applicable standard and class or provide the complete customer specification.
Grades, blanks and drawing parts
Legacy or supplier designations such as K1700, K1701, K1750, K1800 and K1801 must be accompanied by their source specification or required density and properties. They are not automatically equivalent to one another, to an ASTM B777 class or to the grades in the reference tables below. Sourcing can be reviewed for bar, plate, blocks, cut blanks and drawing-defined parts, subject to dimensions and availability.

Selection and inspection
State whether magnetic response, radiation attenuation, balance mass, machinability or another property controls the design. Include dimensional tolerances, surface condition, nondestructive testing and mechanical or density test requirements where applicable. Coupon properties may not represent every location in a large finished part.
