Three Tricks To Teach You How To Buy A Key Lock

  Many consumers are confused about the different key locks on the market, and do not know how to choose a safe, easy-to-use, and durable key lock? The following three points will help you in your key lock purchase:

  see material

  The key lock materials on the market are divided into stainless steel, copper, zinc alloy, iron steel, and aluminum. Stainless steel has good strength, strong corrosion-resistance, and unchanged color, and is the best lock-making material; copper is more versatile, has superior mechanical properties, and is relatively expensive; high-quality zinc alloy is strong and wear-resistant, with very strong anti-corrosion ability, easy to use. Molding is generally used to make mid-range locks.

  see surface treatment

  There are three kinds of general surface treatment: electroplating, spraying, and coloring. These surface treatments can form a protective film on the product, play the role of anti-corrosion and anti-rust, and at the same time make the product more beautiful and durable. Good quality key locks are generally electroplated, with a moderate, very uniform coating, bright colors, and no signs of air bubbles, rust, and oxidation.

  Weigh the weight and listen to the sound

  To weigh the weight, compare the feel, and listen to the sound. The products that cut corners are made of hollow materials and inferior materials. Such materials are very light to weigh, feel bad in use, and have a dull sound; a good key lock is the other way around.
