2124 Plate Bar Block

2124 Plate Bar Block introduction
The 2124 Plate Bar Block is an American brand and the Chinese brand is 2A12. The alloy element of the 2124 Plate Bar Block is copper, which is called hard aluminum. It has high strength and good cutting performance, but has poor corrosion resistance. It is widely used in aircraft structures (skins, skeletons, ribs, bulkheads, etc.), rivets, missile components, truck wheel hubs, propeller elements and various other structural parts. It is an Al-Cu-Mg series.


 
The physical properties of 2124 Plate Bar Block
1, 2124 Plate Bar Block density is small
The density of aluminum and aluminum alloy is close to 2.7g /, which is about 1/3 of iron or copper.
2, 2124 Plate Bar Block has high strength
The strength of aluminum and aluminum alloy is high. After a certain degree of cold working, the strength of the matrix can be strengthened, and the aluminum alloys of departmental grades can also be strengthened by heat treatment.
3, 2124 Plate Bar Block has good electrical and thermal conductivity
Aluminum is second only to silver, copper, and gold in its thermal conductivity.
4, 2124 Plate Bar Block has good corrosion resistance
The surface of aluminum is easy to produce a dense and strong alumina protective film, which can well protect the substrate from erosion. Through artificial anodizing and coloring, forged aluminum alloys with good forging performance or deformed aluminum alloys with good plasticity can be obtained.
5, 2124 Plate Bar Block is easy to process
