Corrosion Resistant Aluminium Round Tube for Power Stations 3A21 H12 D20mm WT1.64mm
Product Description:
Large heat exchangers for big power plants are designed to release
waste heat into the atmosphere so that the machinery that generates
electricity may continue to operate.

3A21 aluminum alloy is one of the most widely used rust-proof
aluminum, the strength of this alloy is not high (slightly higher
than the industrial pure aluminum), can not be heat-treated to
strengthen, so it is used in cold-working methods to improve its
mechanical properties.
Features:
3A21 AL-Mn system alloy: in the annealed state has high plasticity, in the semi-cold hardening plasticity is still good, cold hardening plasticity is low, good corrosion resistance, good weldability, cutting performance is bad. Uses are mainly used for the requirements of high plasticity and good weldability.
Applications:
Large peak cooler
surface condenser
Large heat exchange equipment
condensator
evaporimeter
etc.
Technical Parameters:
The 3xxx series aluminum alloy represents 3003, 3105 , 3A21 mainly. The content is between 1.0 and 1.5, and it is a series with good anti-rust function.
Commonly used for liquid products tanks, tanks, building processing parts, construction tools, a variety of lamps and lanterns parts, as well as thin plate processing of various pressure vessels and pipelines. It has good molding, solubility, and corrosion resistance.

H12 -- tensile strength value corresponds to the intermediate value
between the annealed state O and the 1/2 hard state, called the 1/4
hard state.
