Titanium Fasteners is a low-density, high-strength elements with excellent corrosion resistance. The element can be found in all living things, bodies of water, rocks, soils and somemineral deposites. The most common occurence of titanium is in the form of TiO2 or titanium dioxide, and it is used as a white pigment. Titanium can be alloyed with many popular metals to createstrong lightweight materials for use in estreme conditions. Titanium has the highest strength to weight ratio of any metalic element.
Titanium has high ductility and melting point of 1650°C (3000°F) and has low electrical and thermal conductivity. A major advantage of titanium is that it has twice the strength of aluminium and only 60% of the density. When titanium is machined, it can gall and friction weld to the tool being used.
At room temperature, titanium creates a passive oxide layer that protects it from further oxidation or chemical degradation. The oxide layer protects the material from dilute acids, but concentrated acids will still damage it. It also burns before melting and can only be melted in a complete vacum.
Titanium comes in multiple grades, made of both pure metal and alloys. Each grade has specific uses and properties.
Grade 1 titanium is the most ductile of pure grades. it provides great formability and impact toughness compared to the other grades.
Grade 2 is considered the workhorse of the pure titanium grades because it is available and can be used for a wide range of applicarions.
Grade 3 has a higher strength than Grades 1 and 2 and has a similar ductility.
Grade 4 is the strongest pure titaniumand has increased chemical resistance. It can also be welded easily and is mainly used in medical applications.
Grade 7 is close to Grade 2, but adding palladium decreases the difficulty of fabrication and makes it the most chemically resistant of all titanium alloys.
Grade 23 is pure form of 6AL-4V and is considered the ultimate dental and medical titanium alloy. it has good chemical resistance and is biocompatible so itcan be used in implants.
