With the rapid development of China's machinery industry, more and more industrial factories will begin to use machinery to replace manual work processes. So what do you know about materials commonly used in non-standard automation equipment? It doesn't matter, next, I will introduce it to everyone, let's take a look.

AL6061: (with magnesium and silicon as main alloying elements) 55-65 / KG, medium strength <270Mpa, good corrosion resistance and machinability, 1. nickel plating; 2. anodizing HRC42-55 (a: anode color oxidation , Thickness 8-15u; b: anodized black, thickness 20-30u; c: hard anodized, thickness 12-20u; d: hard anodized black, thickness 20-30u).

6063: (with magnesium and silicon as main alloying elements) 60 / kg, strength <200Mpa.

7075: (with zinc as the main alloying element) 65 / kg, high strength, twice that of 6061, can be quenched but brittle, and the other properties and surface treatment are the same as 6061. )

2A12: (with copper as the main alloy element) 35 / kg, the old standard LY12, the strength of 470Mpa, heat resistance, making high load parts, is the most commonly used in hard aluminum alloy. + E; x- W7 B) n

5A02: (with magnesium as the main alloying element) 35 / kg, old standard LF2, Japan A5052, typical antirust alloy, high corrosion resistance, good weldability, high plasticity, strength 245Mpa, making medium load and welded components.

Q235A: Old standard A3 steel, carbon structural steel, 7 / kg, easy to rust, general sheet metal parts are treated with baking paint, steps: a: if rust, remove rust first; b: go through degreasing-phosphorus before painting "Chemical-passivation" treatment; c: spray the primer to dry, spray the surface paint; d: bake the sprayed workpiece to form a paint film to protect the workpiece. When spraying paint, you can also "spray powder" and "spray plastic" spraying powder is similar to baking paint; but spraying is thicker than baking paint, hard inside and soft outside, but the adhesion of metal surface is small and the uniformity is poor.

Degreasing: Degreasing; Phosphating: A method of chemically reacting metal with phosphoric acid or phosphate to form a stable phosphate film on its surface to prevent corrosion; passivation: chemical cleaning to prevent corrosion of materials. "

SUS304: 52 / KG, for passivation treatment and surface drawing; machine parts are not recommended because of poor machinability and sticky knives; passivation treatment: comprehensive pickling of stainless steel, passivation treatment to remove dirt, and surface change after treatment It becomes uniform silver-white, which greatly improves the corrosion resistance of stainless steel. )

SUS303: 45 / kg, good machinability, good corrosion resistance, twice the strength of 6061. SUS440C: 160 / kg, high carbon content, quenched HRC> 55, demagnetized after processing, abrasion and corrosion resistance. Demagnetization: SUS440C is magnetic after cold working. It is demagnetized with a high-power demagnetizer.

S136 (H): 35 / kg, (Sweden) quenching hardness HRC45-55, the surface can be processed into mirror surface, demagnetized after processing, corrosion resistance and hardness are lower than 440C; S136H is pre-hardened, hardness HRC30-35 ).

SUS316: stainless steel has good plasticity, toughness, cold degeneration, welding process performance, 316 high temperature strength is good, 316L high temperature performance is slightly worse, but corrosion resistance is better than 316, due to low carbon content and 2%-3% molybdenum, improve Corrosion resistance to reducing salts and various inorganic and organic acids, alkalis, salts, and high temperature strength.

45 steel: medium carbon steel in carbon structural steel, 8-12 / kg, strength: 600Mpa, for rust prevention, oxidation treatment, commonly known as: blue, black. For shaft parts, 50 steel can be used if hardening is required.

SKD11: 46 / kg, mold steel, quenching hardness> 58, high hardness and high wear resistance. "

ASP-23: 520 / kg, high hardness, high wear resistance, high toughness powder high-speed steel, hardness up to HRC60-66, used for precision die punch.

POM: commonly known as "Steel", white 45 yuan / kg, black 65 / kg, stick 55 / kg, antistatic 338 / kg, good abrasion resistance.

UR: 30 / kg, commonly known as "Ultra".

Plexiglass: (PMMA) 28 / kg, has a certain strength and temperature resistance, is brittle, and the surface hardness is not easy to brush.

Bakelite: (epoxy resin laminate) 32 / kg, good electrical insulation, for electrical flooring; galvanized steel plate for electrical flooring

Aluminium profile: for frame construction

Fang Tong: The most commonly used is structural welding Fang Tong (GB / T6728), also known as: square steel pipes.
