Titanium (Ti-6AL-4V-ELI) is ASTM F136 compliant and is a metal that is nearly 100% hypoallergenic. It can be worn by people who are sensitive to other metals without issue, almost all the time - this is why many piercers favor titanium for fresh piercings. Titanium is stronger than steel, but approximately 45% lighter. The thickness of the layer determines the resulting color. Titanium can be sterilized in an autoclave. As stated, titanium is ideal for customers who are sensitive or even allergic to other metals. It will not oxidize, corrode, react to sunlight, or rust under normal use. It can also be left in piercings long-term. Those with hypersensitivity to different metals, such as nickel, should use titanium instead of surgical steel. It is also an ideal choice to have a piercer change the jewelry if a body is having trouble healing a piercing done with surgical steel. Additionally, titanium can also be used in a process called anodization, which enables the piercer to create a wide variety of surface colors such bright pink, bright purple and even a rainbow mix. Anodizing is a process where the jewelry is submerged in an electrolyte solution before voltage is applied, creating layers of colors. The thickness of the layer determines the color of the finished jewelry.
