At present, many door and window products on the market are mainly made of zinc alloy and aluminum alloy. But for some people who don't know about building materials, which of these two materials is better?
At present, many door and window products on the market are mainly made of zinc alloy and aluminum alloy. But for some people who don't know about building materials, which of these two materials is better? Let's learn about it.
Differences between zinc alloy and aluminum alloy
aluminum Alloy has lower density, lighter quality and high strength, so it has good plasticity. Zinc alloy will add zinc, copper, magnesium and other elements, so it has good fluidity, easy welding and corrosion resistance, the composition and function of the two are slightly different.
1. Aluminum alloy
low density, but relatively high strength, close to or over high quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and anticorrosion, widely used in industry, the usage is second only to steel.

2. Zinc alloy
it is an alloy composed of zinc and other elements. Often added alloy elements include aluminum, copper, magnesium, cadmium, lead, titanium and other low temperature zinc alloy. Zinc Alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and the residual waste is convenient for recycling and remelting; But the creep strength is low, it is easy to change the size caused by natural aging. Melt preparation, die casting or pressure processing into materials. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy.

generally, aluminum alloy doors and windows are more durable, with lighter quality and high strength, and high corrosion resistance and durability. Aluminum profile has good ability to resist atmospheric corrosion, is not afraid of humidity, is not afraid of sunlight, is not deformed at high temperature, is not brittle at low temperature, does not burn, does not age, can be lightning protection, lasting stability, suitable for various climate environments.
Each of the two materials has its own advantages. The specific choice depends on your own preferences.
