View DetailsBenefiting from excellent product performance and stable quality, our products are extensively utilized in various high-end fields across the globe.
Providing high-purity, biocompatible, and wear-resistant ceramic components meeting stringent hygienic and sterile operational requirements.
Powering EV inverters, fast-charging infrastructure, and laser semiconductor modules with superior thermal conductivity.
Supplying structural ceramics engineered for extreme thermal shock, high mechanical stress, and rigorous military-grade durability.
Adhering to the core principle of "creating value for customers", Qiangguang provides customized and cost-efficient advanced ceramic solutions tailored to specific demands, supported by strict full-process tracking.
Products are sold nationwide and exported to Italy, the United Kingdom, Australia, Japan, Malaysia, Thailand, Hungary and other countries, establishing long-term, stable partnerships worldwide.
Committed to delivering high-quality products at reasonable prices, backed by high-quality after-sales services to promote continuous quality improvement.
As modern power electronics and high-frequency communication systems push operational boundaries, traditional substrate materials struggle with thermal dissipation and mechanical reliability. Yixing Qiangguang Ceramic Materials Co., Ltd. leads the industry by supplying wholesale silicon nitride ($Si_3N_4$) substrates that combine exceptional thermal conductivity with unmatched fracture toughness.
Achieving thermal conductivities ranging from 90 W/mK to over 170 W/mK, our silicon nitride substrates effectively dissipate heat from high-density power modules, IGBTs, and EV power controllers.
With a fracture toughness exceeding 6.0 MPa·m1/2 and high flexural strength, $Si_3N_4$ resists thermal shock and mechanical vibration far better than alumina or direct-bonded copper alternatives.
Offering superior dielectric breakdown strength and low electrical loss at high frequencies, ensuring safe isolation in high-voltage industrial and automotive environments.
Silicon nitride offers the optimal balance of high thermal conductivity (approaching aluminum nitride) and exceptional mechanical strength/fracture toughness (surpassing both alumina and aluminum nitride). This prevents substrate cracking during extreme thermal cycling, making it ideal for electric vehicle power modules and railway traction systems.
Yes. As an integrated manufacturer with complete in-house capabilities from powder sintering to precision machining, we offer custom sizing, thickness grading, and advanced metallization options (such as AMB - Active Metal Brazing) tailored to exact client specifications.
We routinely export to Italy, the UK, Australia, Japan, Malaysia, Thailand, Hungary, and numerous other global markets. All shipments are packed in industrial-grade, shock-absorbent export packaging compliant with international freight and customs standards.
We implement a strict full-process quality tracking system from raw material powder formulation to final sintered product inspection. Advanced testing equipment measures density, thermal diffusivity, and mechanical strength for every production lot.
