Problems solved by technology

[0002] With the increasing requirements for high-strength aluminum alloys in various industries, especially for a series of requirements such as high load, light weight, high strength, high toughness, high modulus, good corrosion resistance and welding performance, and the aluminum alloy The scope of application of aluminum alloy is getting wider and wider, and it plays a vital role in all walks of life. At present, the composition elements of aluminum alloy materials are also increasing, and even a large number of expensive rare elements are added, which greatly increases the cost, and The difficulty of recycling and other problems, in order to reduce the cost without reducing the performance of the aluminum alloy, has become the most difficult problem to solve at present

Abstract

The invention discloses a door / window-coated nickel-chrome alloy coating. The nickel-chrome alloy coating comprises the following chemical components in percentage by weight: 1.21-1.23% of C, 0.53-0.57% of Zn, 4.32-4.35% of Cu, 0.25-0.28% of Mg, 0.55-0.58% of K, 22.3-22.5% of Cr, 0.21-0.23% of Si, 1.52-1.55% of Fe, 0.23-0.25% of Co, 8.4-8.6% of Al, 4.65-4.68% of rare earth and the balance of Ni and micro-impurity. The door / window-coated nickel-chrome alloy coating has the advantages that the strength of door / window can be improved, the high temperature resistance is good, and friction and corrosion resistances are also achieved; the nickel-chrome alloy coating can be used under bad environment, and the service life is long; a provided heat treatment process not only can reduce the machining cost, but also can shorten the machining cycle.
