China Titanium Series Proveedores
The characteristics of titanium the most attractive is that they high strong - mass ratio. Their quality with only 57% of the volume of steel, the strength can and after heat treatment of iron carbon alloy comparable. Titanium is manufacture aerospace, jet aircraft and missile ideal material. But it is the biggest drawback is just the cost is too high. Unless have no choice, it is not encourages the use of titanium as fastener material.
Titanium alloy in poor conditions showed superior corrosion resistance, this also is it application in chemical equipment manufacturing main reason. It has a good high and low temperature properties, not magnetization sex and low coefficient of thermal conductivity and coefficient of thermal expansion.
Pure titanium is not heat treatment. Generally speaking, almost no fasteners use pure titanium as raw materials.
There are a lot of titanium alloy, mostly of monopoly. Research shows that, only a small part of the plane light titanium alloy for manufacturing thread class fasteners.
Ti - 6 al - 4 v is heavy load alloy, this kind of metal fastener minimum tensile strength for 135000 psi, has high strength and satisfactory toughness.
Ti - 6 al - 4 mn has a lot of creep ability, easy to forging. Its strength characteristics and Ti - 6 al - 4 v alloy quite, but toughness is a bit poor.
Ti - 1 al - 8 v - 5 fe tensile strength is about 200000 psi. It is important to stress its prominent strong - mass ratio, the metal fastener tightening force and has 350000 psi tensile strength of the same quality steel fasteners quite.
The other two kinds of titanium alloy - Ti - 6 al - 12 zr and Ti - 6 al - 6 v - 2 sn sometimes will be used for fastener manufacturing.
Strength characteristics
Titanium alloy system outside thread fasteners the mechanical properties of the guide in the B - 158 pages of ASTM F468, nut in B - 184 pages of ASTM F467 in. In these norms, Ti - 6 al - 4 v alloy recognition alloy number is five.
