A. Hi Gangal,

Chemically pure titanium is graded by strength, with grade 1 being the least strong, and grade 4 the strongest. Some manufacturers claim their rack tip are made of Grade 4, and that seems to make sense to me for the tips and teeth. I see other manufacturers offering grades 1 and 2.

My guess is that Grade 4 will prove more durable for tips and teeth, but for the remainder of the rack it doesn't matter, and Grade 1 will be least expensive.

Further opinions and comments welcomed.

Luck & Regards,
