Superior Thermal Performance

Superior Thermal Performance

The exceptional thermal characteristics of high density graphite rods set them apart as premier components in high-temperature applications. Their remarkable ability to maintain structural integrity at temperatures exceeding 3000°C is complemented by an outstanding thermal conductivity ranging from 100-140 W/m·K. This superior thermal performance enables rapid and uniform heat distribution, crucial for processes requiring precise temperature control. The material's low coefficient of thermal expansion, typically around 2.6-3.5 × 10^-6/°C, ensures minimal dimensional changes during heating and cooling cycles, maintaining process stability and product quality. This thermal stability is particularly valuable in applications such as semiconductor production and metal casting, where temperature uniformity and dimensional consistency are critical factors for success.
Enhanced Mechanical Properties

Enhanced Mechanical Properties

High density graphite rods boast exceptional mechanical properties that make them ideal for demanding industrial applications. Their compressed structure results in superior compressive strength, typically ranging from 100-140 MPa, enabling them to withstand significant mechanical loads without deformation. The material's high modulus of elasticity, combined with excellent wear resistance, ensures long-term dimensional stability even under challenging operating conditions. These mechanical properties are particularly beneficial in applications such as continuous casting and metal forming processes, where the material must maintain its structural integrity while subject to both thermal and mechanical stress. The rods' ability to resist deformation and maintain their shape under load contributes significantly to process reliability and product quality.
Chemical Resistance and Purity

Chemical Resistance and Purity

The outstanding chemical resistance of high density graphite rods makes them exceptionally valuable in corrosive environments and high-purity applications. Their inert nature allows them to resist attack from most acids, bases, and molten metals, ensuring long-term stability in aggressive chemical environments. The high purity levels, often exceeding 99.9%, make these rods ideal for applications where material contamination must be minimized, such as semiconductor production and nuclear applications. The low ash content and minimal impurities ensure consistent performance and reduce the risk of product contamination. This combination of chemical resistance and high purity is essential for maintaining product quality and process reliability in sensitive industrial applications.
