Selection of materials for safes
Copper is one of the most widely used lock material, its good mechanical properties, corrosion resistance and processing properties are good, and the beautiful color, especially copper forging handles and other lock trim, smooth surface, good density, no pores, trachoma. Firmness and rust, can be used as 24 karat gold plated or gold surface treatment, is magnificent, elegant, add color to the Home Furnishing. Commonly known as cement cabinets, generally for low priced safes selection of materials, according to national standards for the use of not less than 3MM of steel + cement foam cavity made. Because of the existence of cement, this kind of safe is rather stupid, but it is also vulnerable to the damage of the bit and lose its anti-theft function. Because of the fierce competition, there are illegal household after appearance treatment to do outside the iron clip bag is a live cement, drill wear, anti-theft ability is very low. Not recommended to buy
From a durable point of view, the best material should be stainless steel, especially for surface materials, the brighter the use. Its strong strength, corrosion resistance, color unchanged. But there are many kinds of stainless steel, mainly divided into ferrite and austenite. Ferritic stainless steel has a magnetic, commonly known as stainless steel, long time, the environment is not good will rust, only austenitic stainless steel will not rust, identification method is very simple, with a magnet to try to identify.
According to the national standard GB10409-2001, "anti-theft safe" for anti-theft safe material requirements are: anti-theft safe use of steel, its tensile strength should be no less than 345MPa.The national public safety industry standard "GA166-1997" on the safe anti-theft anti-theft safe box material requirements are: the use of ordinary low carbon steel box, steel plate thickness should be not less than 6 mm; making use of low carbon alloy steel box, steel plate thickness should be not less than 4 mm.
