2. Anti-rust aluminum: mainly Al-Mn series and Al-Mg series alloys. Because of its insignificant aging strengthening effect, it is not suitable for heat treatment strengthening, but it can be worked hardened to increase the strength and hardness. The main performance characteristic of this type of alloy is its excellent corrosion resistance, so it is called anti-rust aluminum.
3. PA: Polyamide has high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, self-lubrication, shock absorption and noise reduction, oil resistance, weak acid resistance, alkali resistance and general solvent resistance, electricity Good insulation, self-extinguishing, non-toxic, odorless, good weather resistance, poor dyeability.
4. Q235: Carbon structural steel with a yield point (σs) of 235MPa. As the thickness of the material increases, its yield value decreases. Due to the moderate carbon content, the overall performance is better, the strength, plasticity and welding properties are better matched, and the use is the most extensive.
5. LED: Its basic structure is a chip of electroluminescent semiconductor material, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with silver or gold wire, and then seals with epoxy resin around it. Play the role of protecting the inner core wire, and finally install the shell, so the LED lamp has good seismic performance.
