What are the commonly used hardware materials? What are their respective properties?
Aluminum alloy (A5052), ----O, H32, H34, H36, H38HCharacteristics: good corrosion resistance, corrosion Younai, formability and good weldability, good anodic treatment. Purpose: household appliances, optical instruments, clocks, gear panel, vehicle and ship materials, trucks, cargo plate've etc..
Hardware is a kind of building materials industry, including construction hardware, mechanical hardware, spraying equipment, kitchen facilities, bathroom facilities and hardware fittings.The traditional hardware refers to hardware, refers to iron, steel, aluminum and other metal, through forging, calendering, cutting, and so on physical processing made from various metal devices. There are many kinds of hardware products, and the specifications are not the same. They occupy an important position in furniture decoration.Big hardware includes steel plate, steel, flat iron, steel bar, universal channel iron, I-iron and various types of hardware, building hardware, tin, lock nails, wire, steel wire, steel wire cutting, home hardware, tools etc.. On the nature and use of hardware, iron and steel materials, non ferrous metal materials, machinery parts, transmission equipment, auxiliary tools, working tools, construction hardware, household hardware and other eight categories are to be considered.
Hardware, the past is gold, silver, copper, iron, tin, five kinds of metal materials collectively.Now, the hardware products are usually divided into two major categories: big hardware and hardware.Big hardware generally refers to metal plates, pipes, profiles, bars and wire;The hardware mainly includes coating material (such as tin), wire coating (such as Tie Si), a variety of small standard parts (such as fastening screws), non standard parts (such as wood screws) and various gadgets (such as a screwdriver) and so on.
Stainless steel (SUS)SUS301----1/2H, 3/4H and H features: good corrosion resistance, good cold workability, non magnetic in the burn back state, and magnetic after cold working. Application: used for vehicle parts, springs, buildings, hardware, etc..SUS304----1/2H, 3/4H and H characteristics: good corrosion resistance, low temperature strength, good mechanical properties, good work hardening, heat treatment, non hardening, non magnetic. Uses: household appliances, building decoration, vehicle parts, medical instruments, food industry and chemical industry.
Cold rolled steel sheet (SPCC), ----SAE1006, SAE1008Features: smooth finish - good mechanical properties, smooth surfaces with fine abrasive lines. Blunt surface treatment with good mechanical properties, fog, matte finish.Purpose: because it contains a small amount of residual elements, corrosion resistance and excellent, so it is widely used in galvanized or colorOn galvanized steel sheet, suitable for hardware products with special surface requirements.
