Ultra-Formable 260 Brass Round Tubes

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

Tubes with 0.014" and 0.45 mm wall thicknesses allow you to create telescoping tubes; each tube fits inside the next larger size.
