The mirror aluminum sheet


1.Pure aluminum plate

Pure aluminum plate series common code has 1050, 1070, 1085.

Among all aluminum plate series, pure aluminum plate series belongs to a series with the most aluminum content.

Purity can be more than 99.00%.

As there are no other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in the conventional industry.

The majority of the 1050 and 1070 series are in circulation.

2.Alloy aluminum plate

5××× series alloy aluminum plate: represents 5005 aluminum plate, 5657 aluminum plate series.

5××× series aluminum plate belongs to the commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%.

It can also be called aluminum magnesium alloy.

The main features are low density, high tensile strength and high elongation.

The weight of al-Mg alloy is lower than other series in the same area, so it is often used in aviation, such as aircraft fuel tank.

It is also widely used in conventional industries.

The processing technology is continuous casting and rolling, which belongs to hot rolled aluminum plate series, so it can be further processed by oxidation.

In China, the 5××× series aluminum plate is one of the more mature aluminum plate series.

5××× series alloy aluminum plate has a good mirror effect.

Distinguish between aluminum sheet editors

Mirror mirror aluminum board is divided into many kinds, grade from low to high, including film mirror aluminum, domestic polished mirror aluminum, imported polished mirror aluminum, imported oxidized mirror aluminum, and super mirror aluminum plate.

According to the characteristics and positioning of your products to choose suitable for your reflector, if you want to do high-end quality products, then choose imported mirror, low-end, choose domestic.

The feature of domestic mirror is that the surface is not protected, the mirror rate will change with time, the price is cheap;

The characteristics of imported products are stable reflectivity, 86% ordinary mirror and 95% super mirror, the price is a little more expensive.

The best mirrors are German and Italian. Japanese mirrors are non-oxidized and are standard sheet material with high wear and tear, but their unique textured effect is favored by shell manufacturers of electronic products.

Simple test methods:

After tearing off the protective film, touch the mirror surface with your finger. The sweat stains on your finger will remain on the mirror surface, but after wiping it with dry cloth or paper towel, the fingerprint will be wiped clean without leaving any trace.

Domestic mirror aluminum plate is different, leaving the finger will be wiped more dirty, finally unable to restore the mirror effect.

There are other ways to test:

Hold a small aluminum plate to your ear and bend it quickly. If a slight tearing sound can be heard, it is proved to be imported aluminum oxide plate, and vice versa, it is the ordinary polished plate made in China.

The oxide film on the surface of the imported aluminum mirror is similar to corundum. Due to the difference in structure between the aluminum and the oxide film, the oxide film will burst and make a slight tearing sound when it is bent.
