6061 6351 6082 aluminum tubing

6061 aluminum tubing can be enhanced by heat treatment, with moderate plasticity under annealing, rigid quenching and heat condition, good weldability of spot welding, and the tendency of forming intercrystalline cracks in aluminum tubes when welding and argon arc welding. The cutting properties of aluminum tubes are good after hardening and cold hardening and bad in anneal state.
