Ninja Prepper has been designing and selling Titanium products for several years, and we have tested a variety of titanium alloys to see what provides the best combination of strength, weight and cost for our customers who demand the highest quality products.
First, a quick primer on Titanium alloy. Many products, including ours, are labeled as being made of "Titanium". In scientific terms these products are not pure Titanium but are actually a Titanium alloy. An alloy is a blend, often created to increase strength or improve the ability to shape or form the metal. Most quality Titanium products on the market are made of an alloy that is almost pure, but has some combination of Aluminium, Vanadium or Iron mixed in with it. Lower quality products may have significant amounts of these other elements to reduce cost.
All Ninja Prepper mugs, sporks and carabiners are created with Grade 9 Titanium Alloy which contains 3% Aluminum and 2.5% Vanadium.
Composition of Grade 9 Titanium Alloy
This blend of metals produces a Titanium that is roughly twice as strong as stainless steel at half the weight.
Another common alloy used when additional strength is required is Grade 5 Titanium Alloy. It includes twice as much aluminum, and also adds a small amount of iron. It is more difficult to work into complex shapes, but has added strength which makes it popular for aircraft and military applications.
Here are some details on more popular grades:
Grade 1 - 4
Grades 1-4 are commercially pure. They are used for applications requiring extreme corrosion resistance or low cost.
Contains 5% aluminium and 2.5% tin.
Contains 3.0% aluminium and 2.5% vanadium.
Contains 4% aluminium, 2.5% vanadium, and 1.5% iron. This grade was created in the 1990s for use in military armor plating applications.
