The color of a cutting blade mainly represents its purpose and performance, and is also used to improve the market appeal and operational efficiency of the product.
Functional color: For example, black cutting blades are often used to cut stainless steel because of their outstanding high temperature resistance; green cutting blades are used to cut ordinary steel because they remain sharp during cutting and the cut does not turn black.
Market and aesthetics: Manufacturers use colorants to increase the beauty and appeal of their products, and also choose different colors according to market demand. For example, black and green cutting blades are popular in the Asian market, while yellow cutting blades are commonly used in regions such as Africa because of their low price.
Performance enhancement: Colorants are used not only to improve the appearance, but also to improve the actual performance of the cutting blade. For example, colorants such as iron oxide red and chromium oxide green enhance the high temperature resistance and light resistance of the cutting blade, thereby extending its service life and improving work efficiency.
In short, the color of the cutting blade is a combination of function and aesthetics, helping users quickly identify and select the cutting blade suitable for a specific cutting task.
