Hotel lock panel material is essential

1, space aluminum - easy processing and molding; low development costs; soft texture, easy to deformation; low strength, poor impact resistance; color and cold monotonous, easy oxidation, short life; simple style, low price of the material itself, poor fire protection , better than dipping.

2, zinc alloy - easy casting process, low development cost; style, surface color and more; low strength, poor impact resistance, poor rust resistance, internal materials prone to oxidation, there are spots; crisp and fragile, not prevent Drilling, tamping, anti-saw; material itself is of low value; not resistant to low temperature; poor fire protection.

3, stainless iron - stainless iron is chromium and nickel, and stainless steel is both chromium and nickel, because nickel is a more stable element, then its corrosion resistance is naturally stronger than stainless steel a lot of! Since nickel is more expensive, stainless steel is higher in cost than stainless steel, and the difference in corrosion resistance makes stainless steel 1/4 to 1/3 higher than stainless steel.

4, stainless steel - strong corrosion resistance, high strength, fire prevention, anti-drilling, anti-mite, anti-saw, anti-impact, long service life; uniform texture, high density, no air hole, trachoma, bright and uniform color, delicate; green The production process is complicated and the development cost is high. Stainless steel will not rust mainly to see the nickel content inside. 304 has 8 nickels and 201 has less than one. The probability of rust is greater. Second, look at your environment over there. Stainless steel is afraid of acid, alkali, oil, and salt.

Give everyone a reminder that stainless steel should be cleaned regularly. Just use clean water. Do not use detergent or detergent.

5, brass - strong corrosion resistance, uniform texture, good density, no pores, trachoma, bright and uniform color, delicate; production process is complex, high development costs; if the gold plating is magnificent.
