Ultra-Formable 260 Brass Rectangular Tubes

- Yield Strength: Not Rated
- Hardness: Not Rated
- Temper: H02 (1/2 Hard) to H03 (3/4 Hard)
- Heat Treatable: No
- Specifications Met: ASTM B135
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. Each tube fits inside the next larger size for creating telescoping tubes.
