Yes, the quality is better, the material is relatively novel, you can consider buying.

Aluminum alloy has low density, but relatively high strength, close to or more than high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, is widely used in industry, and the amount of use is second only to steel.

Aluminum alloy can be divided into two categories: deformed aluminum alloy and cast aluminum alloy according to the processing method

Deformed aluminium alloys can withstand pressure machining. It can be processed into aluminum alloy of various shapes and specifications. It is mainly used in the manufacture of aviation equipment, doors and windows for construction, etc.

Deformed aluminum alloy is further divided into non-heat-treatable strengthened aluminum alloy and heat-treatable strengthened aluminum alloy. The non-heat treatment strengthened type can not improve the mechanical properties through heat treatment, but can only be strengthened by cold working deformation, which mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and anti-rust aluminum. Heat-treatable strengthened aluminum alloys can improve mechanical properties by heat treatment methods such as quenching and aging, which can be divided into duralumin, forged aluminum, superduralumin and special aluminum alloys.

Cast aluminum alloy can be divided into aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy, aluminum-zinc alloy and aluminum-rare earth alloy according to chemical composition, among which aluminum-silicon alloy has eutectic silicon aluminum alloy, eutectic silicon aluminum alloy, monoeutectic silicon aluminum alloy, and cast aluminum alloy is used in the as-cast state.

Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.

The 2008 Beijing Olympic torch "Xiangyun" is an aluminum alloy.

The main raw material of nano alumina ceramics is nano alumina, which has been applied in many high-tech fields and industries because of its wide range of functions and power.

There are two typical applications in the electronics industry, high-pressure sodium lamp light-emitting tubes and nano-alumina ceramic sensors.

The high-pressure sodium lamp light-emitting tube is a nano-alumina transparent body formed by polycrystalline opaque nano-alumina, which is applied to the high-pressure sodium lamp light-emitting tube, and the lighting efficiency is twice that of mercury lamp, thus opening up a new way to improve the lighting efficiency. Transparent nano alumina fine ceramics can not only transmit light, but also have high temperature resistance, corrosion resistance, high insulation, high strength, low dielectric loss and other properties, is an excellent optical ceramic, can also be used as microwave oven windows, etc.

The nano alumina ceramic sensor uses the structural characteristics and characteristics of nano alumina ceramics such as grains, grain boundaries, and pores as sensitive components, which are used in high temperature and corrosive gas environments, so that the detection and control information is accurate and rapid. From the type of application, there are sensors for temperature, gas, humidity, etc.

Nanomaterials were discovered and studied at the end of the 20th century. Since then, nanomaterials have quickly become a high-tech product that has attracted much attention in the 21st century, and are increasingly being applied to different fields. It can be said that an era of nano has quietly opened.

Nano alumina has a series of excellent properties such as high mechanical strength, large insulation resistance, high hardness, wear resistance, corrosion resistance and high temperature resistance, which is widely used in various industries such as ceramics, textiles, petroleum, chemicals, construction and electronics, and is currently the most widely used chemical material in oxides, with large production and sales.

Synthesis process of low-cost nano-alumina.

Abstract:Aluminum nitrate and ammonia bicarbonate were used as the main raw materials to prepare nano-alumina powder by chemical precipitation in ultrasonic field. The reactants were studied experimentally.

The effect of dropping sequence and method on the particle size of alumina was optimized by orthogonal test method, and scanning probe microscopy (SPM), XRD and TEM techniques were used.

The powder was characterized. The results showed that the aluminum nitrate solution was added to the ammonia bicarbonate solution at one time to obtain smaller nanoparticles, and the system contained B.

Alcohol can reduce the occurrence of agglomeration. Under 900, the ratio of the amount of aluminum nitrate to ammonia bicarbonate is 1 8, and the mixing method is that aluminum nitrate is added at one time.

In ammonia bicarbonate solution, when the volume ratio of water to ethanol is 1 1, nano-alumina powder of about nm can be obtained during calcination.
