We are OEM manufacturer for titanium blade-rocess titanium blade and knife, shaft, barb, and other titanium products for diving, the blade or knife is made by titanium alloy material, it is never stainless in sea water, and it is nonmagnetic and light very much. It is titanium alloy material, it is very light. The benefits that make Titanium so well suited for knives, Titanium has many attributes that make it a superior material when it comes to making knives and other tools. These include: Corrosion Resistance -Titanium is corrosion proof in all naturally occurring environments. The MPK SEAL knife has been soaking in seawater four years without a hint of corrosion. Weight - Titanium is 40% lighter than steel Heat and Cold Stability-Titanium is 800 degrees F more thermally stable than steel. It will not break in subzero weather, whereas, steel will shatter. Wear/Abrasion Resistance-With three times the abrasion resistance of steel, titanium is a self-healing metal that forms an oxide ceramic skin over itself when scratched. This gives it the ability to resist wear contact with outside materials such as dirt, sand, ice, mud, nylon webbing, rope, etc. Superior Ductility-The Navy SEALs have been unable to break titanium MPK in over ten years of service. With 12% elongation coupled Tough-Titanium is tough at both high and low temperatures. It resists breaking, cracking or chipping under impact or stress. Flexibility-Titanium may be flexed or bowed repeatedly without undergoing rupture. It has 1/2 of the modulus of steel;therefore, it will bend at least twice as far before breaking. Non-Poisonous-Titanium is non-poisonous and biologically inert. It is used as human replacement joints. Strength-to-Weight Ratio-Titanium has superior strength-to-weight ratios when compared to either steel or ceramic. It is the alloy of choice for aircraft. Non Magnetic-Titanium is magnetically inert, and is used by the Navy SEAL and Explosive Ordinance Disposal units (EOD) to defuse magnetically triggered mines.
