As a metal nameplate manufacturers and a custom nameplate company, we are familiar with aluminum and stainless steel. As below, we will explain to you how to tell aluminum nameplate from stainless steel nameplate under our professional point of view.

1. Different weight: The density of aluminum is relatively small, so it is much lighter than stainless steel, while stainless steel is relatively heavy. This can be directly weighed by hand or weighed to distinguish.

2. Different hardness: the chemical structure of aluminum is not very stable, while the chemical structure of stainless steel is relatively stable. Compared with aluminum, stainless steel has strong corrosion resistance, high temperature resistance, acid and alkali resistance and oxidation resistance, so during use, the hardness of SUS is relatively hard, and it is not easy to deform and rust.

3. Different prices: stainless steel with the same square meter area is much more expensive than aluminum. While aluminum is more cheaper.

4. Different degrees of high temperature resistance: the melting point of aluminum alloy is 500~800°, while the melting point of stainless steel is 1200~1500°, so stainless steel is more resistant to high temperature.

5. Different colors: aluminum is a silver-white pure metal with a dull color, while stainless steel is a bright silver or iron-gray metal with a brighter color.

6. Different magnetic properties: aluminum is not magnetic, while stainless steel with weakly magnetic.

7. Different plasticity: aluminum is softer, while stainless steel is harder, so the plasticity and processing performance of aluminum are stronger than those of stainless steel.

8. The degree of welding is different: stainless steel is better for welding than aluminum, the thickness is thicker, and it can withstand the high temperature of welding.

9. Different surface treatment: stainless steel surface treatment includes mirror bright, natural whitening, coloring, brushing, passivation, vacuum plating and other surface treatments; aluminum alloy treatment includes sandblasting, polishing, car pattern, brushing, electroplating, spraying, anodizing surface treatment and so on .

10. Different industrial applications: aluminum is soft in texture and can be used in traffic signs, house numbers, and wine signs; stainless steel is hard in texture, has strong pressure resistance, and has strong outdoor adaptability, and is used in automobiles, trains, high-speed rail industries, water industry, construction industry, industrial facilities, general household appliances industry, etc.
