FT-5
Alloy-TiC FT-5 is a precipitation hardening type nickel base super heat resistant alloy. It has spherical high hardness with dispersed and sintered TiC particles. It can be applied in corrosive and oxidizing at high temperatures where generally not used tool steel or other materials as a product.
It will lose strength at a temperature of about 700 ° C, but it can be used up to 980 ° C This alloy also has a low coefficient of friction due to the spherical TiC particles, which minimizes pick-up, galling and chipping during high-speed or high-pressure contact and friction work

- Comparison of characteristics of inconel X-750
- inconel X-750 is a precipitation-hardening Ni-base Super-Alloy, which has high temperature strength, corrosion resistance and oxidation resistance. Applications are for jet engines and rocket parts. Loss of strength at a temperature of about 650 ° C, but can be used up to 700 ° C. The table shows the characteristics of the Inconel X-750. Comparing the mechanical properties of Alloy-TiC FT-5 and Inconel X-750, FT-5 exhibits a hardness of 1.7 times that of Inconel X-750 at a temperature of about 600 ° C as shown in Fig. 2 times higher abrasion resistance. Therefore, it is predicted that the life expectancy applied to a die of copper extrusion is twice as long as that of Inconel.
