Spherical GRcop-42 alloy powder for 3D printing

Specification of GRcop-42 alloy powder:

Alloy name:GRcop-42

GRcop-42 alloy powder is a highly conductive metal alloy powder composed of elements such as copper (Cu), chromium (Cr), molybdenum (Mo), and niobium (Nb). GRcop-42 alloy has very high thermal conductivity, high strength, and good creep resistance and thermal expansion coefficient, maintaining good stability at high temperatures。

Size:15-45um, 15-53um, 20-63um, 63-106um (various particle sizes can be customized according to customer requirements)

Color: red copper

Shape:spherical

Cu:63-68%, Cr:0.5-1.5%, Mo:0.5-1.5%， Nb:0.5-1.5%, Mn:<0.5%. Fe<0.5%, Sn<0.2%

Application of GRcop-42 alloy powder:

GRcop-42 alloy powder is a copper alloy powder specifically used for additive manufacturing. 14vol% Cr2Nb enhances the absorption of near-infrared laser at low temperatures, thereby increasing the density and surface roughness of the material. The printing density of GRCop-42 exceeds 99.9%, and the surface roughness Ra is 3-4 μ m; In contrast, pure copper reaches Ra=18-30 μ m with a density of 95%, while CuCrZr reaches Ra=10-16 μ m with a density of 99.8%. High tensile strength and stable precipitation structure at high temperatures can be used for applications that require high strength and high temperature resistance, such as rocket engine combustion chambers and fusion reactor components.

Packaging: ordinary packaging such as aluminum foil bags/plastic bottles/iron drums, vacuum packaging or inert gas filled packaging, etc

Storage conditions:
GRcop-42 alloy powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
