TRUER SPHERE – H0001 CoNiCr Powder
High-Entropy Alloy (HEA) powder is technical expertise of Truer. We mainly engaged in the R&D and production of high-entropy alloy powder for high-end 3D printing by the production process of VIGA, EIGA and PREP.
High entropy alloy (HEA) are defined as alloys that have at least three principal elements and the concentration of each element is between 5 and 35 at.%. Under the effects of a high mixing entropy, they easily yield the formation of simple solid-solution phases and nanostructures during solidification, rather than many binary and ternary intermetallic compounds or other complicated phases.
Beyond our common high-entropy alloy powders showed in the below, we also manufacture custom HEA alloy powders with novel compositions, in support of developing innovations in the field of additive manufacturing.
Our common HEA powders:
- CoNiCr / H0001
- FeCoNiCr / H0002
- FeCoNiCrMn / H0003
- FeCoNiCrAl / H0004
- FeCoNiCrMo / H0005
- FeCoNiCrTi / H0006
- FeCoNiCrV / H0007
- FeCoNiCrAlTi / H0008
- AlNiCrFeCu / H0009
