CMH implements at reasonable prices from the manufacturer various rolling of wrought aluminium alloys brands AK-5 and АК5св. The provider ensures timely delivery of products to any place specified by the consumer.

Technical characteristics

Aluminium alloys brands AK-5 and АК5св belong to the alloys with a high percentage of copper and silicon. The alloys have good fluidity, providing after grinding with low surface roughness. The considered aluminium alloy are ideal for use in aviazionnoj technique, and the alloy AK-5св — for the production of welding wire used in the welding of aluminum under a layer of flux. Due to the low density of these alloys is able to provide a weight reduction of castings. The distinctive parameters of aluminum alloy AK-5 and АК5св is the increased strength, toughness, rigidity of the walls on the finished product and good heat transfer.
