Problems solved by technology

Not only lacking in precision, but also not strong enough
[0005] Aiming at the shortcomings of traditional aluminum alloys such as low hardness and non-wear resistance, Publication No. 106048379A discloses a method to improve the toughness and elongation of the product by adding rare earth, strontium and other elements into the aluminum alloy.
However, only improving the toughness, elongation and other properties of aluminum alloys cannot make aluminum alloys cope with complex environments.

Abstract

The invention relates to a pipe joint and belongs to the field of metal materials. The pipe joint is made of aluminum alloy, wherein the aluminum alloy is made from the following raw materials of, inpercentage by mass, 0.05-0.1% of Mg, 0.09-0.15% of Mn, 0.12-0.18% of Ni, 0. 07-0.17% of composite carbon, 0.02-0.04% of Zn and the balance Al and impurities. The pipe joint is prepared by alloy smelting, refining and forming, the service life of the pipe joint is greatly prolonged, and the use requirements of different environments can be met.

Description

technical field [0001] The invention relates to a pipe joint, which belongs to the field of metal materials. Background technique [0002] The pipe joint is a connection tool between pipes and a detachable connection point between components and pipes. It plays an indispensable and important role in pipe fittings, and it is one of the two main components of hydraulic pipelines. Pipe joints are used for straight-line connections such as instruments, and the connection forms include socket welding or threaded connections. It is mainly used for small-diameter low-pressure pipelines, used for parts that need to be assembled and disassembled frequently, or used for final adjustment of pipelines using threaded pipe fittings. Pipe joints are often made of wrought iron materials. [0003] Although wrought iron has high strength and is suitable for structural materials, it is easily corroded, and surface electroplating will cause environmental pollution. Therefore, it is more sui...
