Titanium (Ti), chemical element, a silvery gray metal of Group 4 (IVb) of the periodic table. Titanium is a lightweight, high-strength, low-corrosion structural metal and is used in alloy form for parts in high-speed aircraft. A compound of titanium and oxygen was discovered (1791) by the English chemist and mineralogist William Gregor and independently rediscovered (1795) and named by the German chemist Martin Heinrich Klaproth.

The Element Titanium
What Is Titanium?
- A lustrous transition metal widely used by the aerospace industry due to its ability to withstand the harsh condition of outer space.
- It has also become popular with medical manufactures since it is completely non-toxic to the human body and can be safely implanted in the body.
- Most used in: Cutlery, industry, outdoor EDC gear, tools, gifts.
- Material models: Pure Titanium TA1, TA2, 6Al-4V (Grade 5).
- Lightweight and strong – It is as strong as steel and twice as strong as aluminum, but is 45% lighter than steel and only 60% heavier than aluminum.
- Corrosion resistant – It is highly resistant to corrosion even in sea water, aqua regia and chlorine.
- Bio-compatible – It is non-toxic, non-allergenic and perfectly compatible with the human body.
- Durable – It is more durable than gold and has become a popular choice for designer jewelry.

Titanium Surface Finish
High Temperature Crystallization
Titanium material physical structure changes in the different high temperatures, providing various colors showed on these conditions.
Polishing & Oxidizing
- Natural titanium color
- Gold, Black, Rainbow by Physical Vapor Deposition
- Gold, Black, Rainbow, Blue, Green, Pink, Purple by Anodizing
- Gray, Brown by Micro-arc Oxidation
- Thick /hard carburizing surface
- Grey ceramic hardening coating
Sandblasting is powered by compressed air to form a high-speed jet beam to spray the material. Anti-slip, delicate sand clean surface.
The products are placed in a roller filled with stones, different speeds are realized by adjusting the power.
Product surface will appear wild grey after rolling more than 2 hours. A very popular color for outdoor tools, EDC Gear.
Timascus™ is the creation and collaboration of Tom Ferry, Bill Cottrell and Chuck Bybee. The goal was to create a corrosion resistant, non-magnetic lightweight laminated material that would lend itself to adding an upscale look to a knife without the disadvantages of steel damascus.
Consisting of two or more titanium alloys (currently CP and 6AL4V), Timascus is corrosion resistant, non-magnetic, and lightweight. It has the beautiful, upscale look of steel damascus without any of the disadvantages of steel that can disappoint some knife makers and collectors.
The timascus is made by placing these two different alloys of titanium into a metal box, filling the enclosure with inert gas and applying both heat and pressure to have the two alloys to forge laminated together.
When coloring, the current formulation seems to show more contrast using heat rather than anodizing. All current safe coloring techniques can be applied to Timascus. Future alloy combinations will have different color profiles. (It is only meant for knife furniture as titanium does not form carbides and doesn’t harden enough for a sound blade.)
Working Timascus is essentially the same as any other titanium alloy except when milling. The blended types of titanium have different hardnesses sandwiched throughout the barstock. The varying hard and soft areas can cause wear on the cutting edges of tools. Use round-cornered cutters as they hold up better under machining.
Timascus is a beautiful fusion of old world decorative techniques and modern metal-smithing.
