MIM (Metal-Injection Molding) Titanium Sintered Products

Titanium (Ti) is a high-density strength, highly pliant, highly corrosive-resistant material, which in recent years is seeing ever-growing demand. On the downside, titanium is a difficult material to process and also an expensive one. We have applied the fruits of our 10-year track record in metal injection molding (MIM) technology in the development of MIM Ti sintering products.

We propose a method to use materials tailored to your company.

2. Features of MIM Titanium Sintered Parts

(1) Configurations

In forging, it becomes possible to manufacture intricate, near-net shaped sintered products.

(2) Features of Sintered Objects

With a relative density of 97%, the structure of the sintered object is sufficiently advanced.

Figure 3: Microstructure

The mechanical features rival JIS 3-type welding materials (Chart 1). Furthermore, ruptures seen in stretch tests show ductile fatigue fractures that exhibit sufficient tractility.

  MIM Ti Sintered Parts JIS3-type Standard
Relative density (%) 97 100
Elasticity (NPa) 600±20 480~620
Growth (%) 21±2 ≧18
0.2% durability (NPa) 310±39 ≧345
Hardness (Hmv) 240±29

Now, with the Titanium alloy MIM, it has become possible to respond to the demand for high-strength products that have a degree of hardness.
