How and why alloying elements are added to aluminum

Silicon additions to aluminum are commonly used for the manufacturing of castings. The most common appliions for the 4xxx series alloys are filler wires for fusion welding and brazing of aluminum. Magnesium (Mg) 5xxx - The addition of magnesium to aluminum increases strength through solid solution strengthening and improves their strain hardening ability.

Silicon carbide alloy ceramic wear tube, SiC Pipe

Silicon carbide (SiC), also known as carborundum, is a semiconductor containing silicon and carbon. The characteristics of the elastic modulus and thermal expansion are given by the characteristics of the SiC crystal itself, and the thermal conductivity or thermal diffusivity of the silicon carbides tends to be substantially higher than those of the other structural ceramics.
