• ▶【Reliable High-Purity Materials】Our graphite ingots are crafted from premium high-purity, high-density graphite raw materials, featuring ultra-low ash content, a carbon purity of over 99.9%, and a density of 1.80g/cm³ or higher. These superior material properties extend their service life by 30%, making them far more durable and reliable than conventional graphite blocks (Tolerance range: 0~0.05mm / Graphite purity: 99.9%).
• ▶【Practical & Versatile Functions】Our graphite ingots deliver exceptional thermal conductivity, ensuring uniform heat distribution and efficient melting - key to consistent, precise casting results in metalworking projects. Beyond that, they boast impressive durability: withstanding temperatures up to 3000°C, excellent resistance to acids, alkalis, and corrosion, strong impact resistance, a compressive strength of 89 MPa, and a flexural strength of 48.7 MPa.
• ▶【Excellent Flexible Processability】Our graphite blocks offer exceptional processability - they can be easily shaped into various geometric forms while retaining sufficient mechanical strength and impact resistance. Their wear-resistant surface also makes them ideal for use as whetstones or other abrasive tools. Additionally, thanks to their unique material properties, these graphite blocks are highly suitable for crafting graphite crucibles and metal-melting containers.
• ▶【Package Included & Item Size】This set contains 4 high-purity, high-density graphite ingots, boasting excellent thermal and electrical conductivity as well as high corrosion resistance to meet your diverse needs. Besides, each piece measures 50×50×20mm (1.96×1.96×0.78 inches), making it compact and easy to carry in a backpack.
• ▶【Wide Application & Significance】Graphite ingots are integral to numerous aspects of daily life, with their unique properties underscoring their indispensable role. They find extensive use across diverse fields: as electrodes, in electrolysis processes, and for manufacturing sintering molds, graphite furnace components, heater parts, graphite heat exchangers, insulation boards, and various other graphite products.
