4 Pack Tough As Nails 99.9 Percent High Purity Graphite Ingots Set EDM Grade Graphite Blocks Designed For Hard Use Metal Melting Casting Molds Crucibles Surface Milling Measuring 1.96 By 1.96 By 0.78 Inches Per Piece

4 Pack graphite ingots for dependable metal casting use.
✔️ Four dense ingots sized 50x50x20mm (1.96x1.96x0.78in) per set

You score four dense carbon blocks built for heavy industry. These pieces handle tough metal casting and precise milling jobs. Foundries and machine shops rely on them for furnace lining and custom crucible builds. You can snap them onto your workflow quickly.

✅ 99.9 percent carbon purity keeps contaminants out of your melt
✅ Density sits at 1.80 grams per cubic centimeter for steady weight
✅ Thermal conductivity spreads heat evenly across the surface
✅ Resists strong acids and alkalis without breaking down
✅ Handles internal pressures up to 89 megapascals safely

💡 Why do technical crews pick premium graphite for repeated heat cycles? Your gear stays handy when things get hot under pressure. - Carbon matrix absorbs sudden thermal shocks without cracking - Low ash content stops unwanted residue inside your molten mix - Solid mechanical build tolerates constant thermal cycling well - Conductive design pairs perfectly with electrode setups nearby
