How to Identify Titanium Alloy?

1. Spark Test
Grinding titanium produces short, bright white sparks—distinct from other metals—helping identify it quickly.

2.Weight-to-Strength Ratio
Lighter than steel: Titanium has a density of ~4.5 g/cm³, much lower than steel (~7.8 g/cm³), yet remains strong.
Heavier than aluminum: It is about 70% denser than aluminum (~2.7 g/cm³) but twice as strong.
