Material of the knobs

There are currently two mainstream materials for knobs, one is metal, the representative is aluminum alloy, the other is non-metallic, the representative is ABS engineering plastic, and some metals are combined with non-metals.

At present, the most high-end knob is made of aluminum alloy. Almost all products of big brands use this material, such as zinc-aluminum alloy, zinc-magnesium alloy, etc. We all know that brass is an alloy of copper and zinc, which is easy to process. It has good sealing performance and corrosion resistance, and the zinc-aluminum alloy is called "white brass" in the industry. It also has the advantages of easy cutting, easy production, easy grinding, high surface finish, and aluminum produces a white oxide film in the air, hindering the Oxidation, so that the knob can last forever.

Stainless steel is also good, it is better than zinc-aluminum alloy, but stainless steel is not easy to process, and it is a waste of material for knobs. Of course, when we buy, we also need to look at the processing technology. The surface finish is high, matte, and no scratching is a good product.

ABS plastic material is the most common plastic material at present. It is a copolymer of acrylonitrile-butadiene-styrene plastic. It is simple to process, has certain rigidity and strength, and has certain toughness. It is easy to unscrew, and it is heat-resistant. It will not cause the knob to overheat due to the heat conduction of the cooktop panel. It can be said to be a small advantage, but it is not obvious. The ABS material is transparent, and our common bright silver is electroplated, so it is inevitable to wear off the electroplating layer after using it for a long time.

How to replace the knobs?

When replacing the knob, pay attention to the degree of the notch. There are 0 degrees and 45 degrees. 0 degrees means that the notch is upward, and 45 degrees means that the notch is upward left or right. Purchase according to your own needs, and the installation aperture can be 6mm and 8mm. Here, you should measure it in advance when purchasing.
