Graphite holes have good thermal conductivity and high temperature resistance. When used at high temperatures, the heat dissipation expansion coefficient is small, and it has certain heat resistance and rapid cooling performance. It has strong corrosion resistance to acid and alkali solutions and good chemical stability. This will be a convenient combination to meet your DIY needs, casting or refining metals, jewelry, gold, silver and other materials. Gold foil processing is made of high-purity, high-strength, high-density graphite materials and high CNC processing technology. The main graphite used is graphite material for precious metals, and its durability is twice that of ordinary materials.<br><br>Colour:As Shown Material:Metal<br><br>Package Contents: 1 set * Miocololy (7 pcs) Metal Melting Casting<br><br>Only the above package content, other products are not included.
