Stainless steel is good. It is recommended to use stainless steel material, because stainless steel material is not easy to reflect with food. The ten differences between stainless steel and aluminum alloy are as follows:
< br >
Strength-to-weight ratio. Aluminum is generally not as strong as steel, but is also almost a third of the weight. That's the main reason airplanes are made of aluminum.
< br >
Corrosion properties. Stainless steel is made up of iron, chromium, nickel, manganese and copper. Chromium is added as a reagent to provide corrosion resistance. And, because it is non-porous, corrosion resistance is increased. Aluminum has high oxidation and corrosion resistance, mainly due to its passivation layer. When aluminum is oxidized, its surface turns white and sometimes deteriorates. In some extremely acidic or alkaline environments, aluminum can corrode quickly with disastrous consequences.
< br >
Thermal conductivity. Aluminum products have better thermal conductivity (heat conduction) than stainless steel products. One of the main reasons for its use in automotive radiators and air conditioning units.
< br >
Cost. Aluminum is usually cheaper than stainless steel.
< br >
Machinability. Aluminum is quite soft and easy to cut and form. Stainless steel can be difficult to use due to abrasion and wear resistance. Stainless steel is harder to form than aluminum.
< br >
Welding. Stainless steel is relatively easy to weld, while aluminum is difficult.
< br >
Thermal performance. Stainless steel can be used at much higher temperatures than aluminum, which can become very soft above about 400 degrees.
< br >
Electrical conductivity. Stainless steel is a very poor conductor compared to most metals. Aluminum is a very good conductor of electricity. Due to their high electrical conductivity, light weight and corrosion resistance, high voltage overhead power lines are usually made of aluminum.
< br >
The intensity. Stainless steel is stronger than aluminum (assuming weight is not a consideration).
< br >
The effect on food. Stainless steel is less reactive to food. Aluminum can react to foods that may affect color and taste.
1. Stainless steel mold is better. 2. Because stainless steel has high corrosion resistance and wear resistance, it can resist the erosion of chemical substances such as acid and alkali, and has high hardness and strength, it can better maintain the shape and stability of the mold.
In contrast, aluminum alloy molds are slightly inferior to stainless steel in terms of corrosion resistance and hardness. 3. In addition, the stainless steel mold also has good thermal conductivity, which can conduct heat more evenly, which is conducive to the uniform heating and cooking effect of food.
At the same time, the stainless steel material is relatively heavy, which can better stabilize the use process of the mold and improve the service life of the mold.
Therefore, from the perspective of corrosion resistance, hardness, thermal conductivity and stability, stainless steel mold is more suitable for making lunch meat mold.
Stainless steel good
1.Aluminum alloy density is low, but the strength is relatively high, close to or more than high-quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of second only to steel.
2. Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance. It can be strengthened by heat treatment. It is characterized by high hardness, but poor plasticity. But poor corrosion resistance, high temperature softening fast, has excellent thermoplasticity, suitable for forging, so it is also called forged aluminum alloy.
3. Stainless steel is mainly nickel chromium alloy, corrosion resistant. When there are corrosion resistance requirements for things produced, stainless steel will definitely be used. Secondly, the surface of stainless steel can be processed as needed, and the appearance is more beautiful and smooth than that of aluminum alloy.
4, but the cost of stainless steel is higher than aluminum alloy, now there is no lack of money or government public works are basically used stainless steel, in short, beautiful not easy to rust not easy to damage
