SHP 644 offers one of the lowest densities of all beta-titanium alloys and achieves considerable strength after heat treatment.

---

SHP 644 titanium is virtually the same as SHP 38 644 but with one notable exception. Our product is solution heat treated and cold worked rather than cold drawn. While we supply SHP 38 644 in diameters up to 16mm and release it to AMS 4957, SHP 644 offers the same mechanical properties at a much greater maximum diameter (40mm). Note that only SHP 644's chemistry is released to AMS 4957.

Advantages:

The development of our product provides a titanium alloy that offers the same benefits as SHP 38 644 but with increased diameters, which affords engineers improved design flexibility - our material benefits from high strength and exceptional ductility while being highly corrosion resistant. The alloy can be solution-treated (annealed) or solution-treated and aged (STA).

40% strength increase

When solution treated and aged, the alloy still provides good ductility and low modulus of elasticity but with up to 40% increased tensile strength.

Stock Availability:

We stock SHP 644 in solid round bars from 0.630 inch (16mm) diameter to 1.575 inch (40mm) diameter.
