The braze (142) consists of a pure titanium layer and a pure tin layer.

Said system can be used to improve the adhesion of ceramics, intended for pure titanium or titanium alloys, to a structure consisting of pure titanium or a titanium alloy.

Also provided is a novel pure titanium sintered body having high hardness in comparison to a titanium alloy comprising an alloy using the aforementioned pure titanium.

The cathode (12) and the anode (13) are fabricated from metal, preferably from titanium or pure titanium.

The titanium medical implant contains at least 99wt% of pure titanium.

Titanium specifications define properties of pure titanium and titanium alloys.

Kobe Steel produces pure titanium, titanium alloys, flat-rolled products, pipes.

In the disclosed titanium fuel cell separator (10), a carbon layer (2) is formed on the surface of a substrate (1) formed from pure titanium or a titanium alloy.

The rivet body (50) preferably consists of JIS type 1 to type 3 pure titanium, and the mandrel (51) preferably consists of JIS type 2 to type 4 pure titanium or JIS type 60 titanium alloy.

In the disclosed titanium fuel cell separator (10), a carbon layer (2) is formed on the surface of a substrate (1) formed from pure titanium or a titanium alloy.

The coating protects bare titanium and brazed surfaces of the heat exchanger.

The upper part (2) and the lower part (4) are made of pure titanium.

Provided is a novel pure titanium having a strength increased to a level equivalent to that of titanium alloys.

The aim of the invention is to provide a titanium material free from toxic components and with improved mechanical properties relative to pure titanium.

It is the high purity titanium obtained by iodization, so it is called iodization titanium, or chemical pure titanium.
