Prodsuct Introdsuction
2024 Aluminium alloys have strong corrosion resistance characteristics. These alloys are sensitive to high temperatures ranging between 200 and 250°C (392 and 482°F). An increase in strength takes place when these alloys are exposed at subzero temperatures and strength is lost when these alloys are exposed to high temperatures. Aluminium alloys are good low-temperature alloys. It is better in formability in the condition of thermal state, annealing and quenching conditions. The effect is remarkable in the reinforcement of heat treatment, but it’s strict with the heat-treatment process.
The Aluminium Alloy 2024 Round Bar is also known as an aerospace aluminium bars along with extruded and cold-finished aluminium wrought materials. The alloy 2024 round barss facilitate clients’ very good machinability, improved weldability, high-moderate strength, and finest corrosion cracking resistance. Since it has good strength, it has become an excellent part of other barss too. The machinability of aluminium alloy is fine in annealed conditions and heat treatments.
