With the rapid development of modern transportation, the performance of materials is required to be higher and higher. Because of its light weight, good corrosion resistance and high tensile properties, aluminum alloy products have become the research hotspot of transportation materials in the world. 6026 aluminum alloy belongs to medium strength Al Mg SI system aluminum alloy, which can be heat treated and strengthened.
6026 T8 T9 aluminum rod bar is mainly used to manufacture welding structures with high strength and fracture toughness, such as rods, containers, large heat exchangers of transportation vehicles, and parts that cannot be solid solution treated after welding. It can also be used to manufacture sports equipment, etc.
This innovative alloy is developed to meet the environmental protection standards, especially in high-speed automatic machine tools. 6062 alloy has excellent corrosion resistance and high mechanical properties. It is suitable for decoration, industrial oxidation and hot casting. The alloy does not contain Sn, which will lead to the weakening and fracture of the machined part under high pressure and high temperature. 6026 can replace some 6061, 6082, 6064a, 6042, 6262, 6012, 2007, 2030 alloy products
The content of toxic element lead should be strictly controlled. Because lead can contaminate other elements of aluminum alloy. Before and after the melting and casting of lead containing aluminum alloy, it is necessary to clean and wash the furnace, which brings great inconvenience to the production and increases the difficulty of process waste management. In view of customers' demand for high precision and other harsh conditions, our company has produced
6026 T8 T9 aluminum rod bar products that meet all customers' requirements through continuous R & D and trial production, and the quality has met the requirements of European products. Combined with the practical production experience of related cemented carbide, according to the relevant technical performance requirements put forward by customers, we have carried out the preliminary process design and trial production, and summarized the production process system that meets the requirements of customers.
The technological process of
6026 T8 T9 aluminum rod bar is: Casting → extrusion → aging → drawing. 6026-t9 bar has high performance requirements. The dimension tolerance of finished bar is - + 0.005 mm, and the straightness is 0.3 mm every 3 m. 6026 alloy is a newly developed medium strength aluminum alloy, which is widely used. At present, the European ROHS Committee strictly controls the content of lead, so the content of lead should be reduced as much as possible. Considering that the addition of Pb and Bi will consume mg and form Mg2Pb and mg3bi, and their binding ability is stronger than that of Mg2Si, the low Mg content will affect the mechanical properties to a certain extent. Therefore, Mg is properly added in the alloy composition design.
(1) The addition of lead and bismuth in 6026 alloy will consume magnesium, so the content of magnesium should be increased appropriately.
(2) The optimum production process of 6026-t9 high precision bar is as follows: extrusion temperature 500 ~ 515 ℃; The on-line solution temperature is 520 ~ 530 ℃; Aging process 165 ℃ + 8 h.
(3) When the cold drawing deformation is controlled at 1% ～ 2.5%, the product quality can meet the requirements of mechanical properties, dimensional tolerance and straightness of customers, and a higher yield can be obtained.
