treatment of titanium alloy screws and pure titanium screws

In recent years, my country's titanium industry has developed rapidly and has become a major country in titanium production and development. The overall output of titanium alloy screw products in my country is increasing year by year. Titanium alloy screw materials are also widely used in mechanical equipment, electronic equipment, communication equipment, hardware lighting, construction bridges and other industries, and gradually enter the civilian field. Place. Products made of general materials are almost all designed to take advantage of the low density of titanium screws, and are usually used where density requirements and heavy requirements are combined.

Titanium alloy screws are not a high strength material. It has high specific strength. The density of titanium alloy screws is about 50% to 60% of that of 45# steel, but the strength is equivalent. Titanium alloy screws have high strength, good heat resistance and low temperature resistance. Titanium has good corrosion resistance to salt, sea water and nitric acid. It is well-deserved space metal and ocean metal.

Titanium screw

Regarding the phenomenon of titanium screw slipping, we sometimes encounter the overflow of titanium alloy screws, also known as sliding wires. Commonly used on bicycles are threaded holes in aluminum parts such as handlebars, cranks, and seat clamps. Titanium screws and pedal axles are generally acceptable. The perfect restoration is to ream and tap the lower titanium screw inserts, but this procedure cannot be reamed in some places because it is inconvenient and expensive.

The way to make up is to wrap a hemp knife, raw material tape, and apply thread sealant or 502, but the result is that the thread is useless if it is not tightened. Now we introduce a simple fix. As long as it is a small tape measure, an easy-to-pull button, and other useless stretchable things at home, there must be a coil spring in it. Please remove the coil spring before throwing.

If the titanium alloy manufacturer encounters the thread overflow of the titanium screw, you can cut a small section of the coil spring, fold the head, put it into the overflow screw hole, and screw the titanium alloy screw directly into it. Basically, the tightening torque of the original aluminum screw hole can be restored, and the spring can be disassembled repeatedly, and the spring will not fall off. When tightening, you can choose coil springs of different widths according to the size of the titanium alloy screw hole, or put two coil springs into the titanium alloy screw hole.
