Silicon Nitride Ceramic:
The difference between the state of T6 and T651 of silicon nitride aluminum plate is that under normal circumstances, the internal stress of T6 will be relatively large, and the processing will be deformed. The state suitable for processing should be T651. It is stretched on the basis of T6 and eliminated. The main alloying element of the stress 6061 aluminum alloy is magnesium and silicon, and forms a Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing the corrosion resistance; there is still a small amount in the conductive material. Copper to offset the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine grains and control recrystallized structure; in order to improve machinability, lead and antimony can be added. The Mg2Si is solid-dissolved in aluminum, which gives the alloy an artificial age hardening function. The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect. 6061 aluminum plate is used in various industrial structural parts with certain strength, weldability and corrosion resistance, such as manufacturing trucks, truss construction, ships, electric cars, furniture, mechanical parts, precision machining, industrial materials and so on.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
