Benefiting from excellent product performance and stable quality, its products are extensively utilized in various high-end fields, such as food and medical industries, new energy vehicles, laser semiconductors, petrochemical engineering, powder metallurgy, national defense and military, as well as aerospace sectors.
Whether providing high-dielectric aluminum nitride ceramic substrates for next-generation EV power modules or non-wetting aluminium titanate riser tubes for low-pressure aluminum die casting, our materials meet stringent ISO9001 and international performance metrics.
Engineering precision backed by over two decades of material science innovation and international export excellence.
Understanding the transition from traditional metallic alloys to ultra-high-performance ceramic aluminium composites and nitrides.
With the rise of SiC and GaN power electronics, modern semiconductors generate intense thermal fluxes. Traditional copper-clad laminates are increasingly replaced by Aluminum Nitride ($\text{AlN}$) ceramics due to their coefficient of thermal expansion (CTE) matching silicon while providing superior thermal conductivity (>170-230 W/m·K) and electrical insulation.
In non-ferrous foundry operations—especially aluminum alloy casting—conventional metals degrade rapidly under thermal fatigue and molten metal corrosion. Aluminium Titanate ($\text{Al}_2\text{TiO}_5$) has emerged as the definitive global standard for riser tubes, dosing nozzles, and sprue bushings due to its outstanding thermal shock resistance and non-wetting properties.
The global battery manufacturing sector (lithium iron phosphate LFP synthesis) requires ultra-pure, wear-resistant grinding media to eliminate metal contamination. High-purity Alumina ($\text{Al}_2\text{O}_3$) and Ceria/Yttria-stabilized Zirconia ceramics provide zero-chemical-contamination wet milling, driving process yield in energy storage production.

While metallic aluminum offers lightweight structural strength, its low melting point (660°C) and soft surface wear limit its application in harsh industrial environments. Technical Ceramic Aluminium compounds solve these limits:

Expert technical answers regarding ceramic aluminium manufacturing, material selection, and procurement.
While both are aluminum-based technical ceramics, Aluminum Nitride ($\text{AlN}$) offers vastly higher thermal conductivity (up to 230 W/m·K compared to Alumina’s 25-30 W/m·K) and a CTE closely matching silicon substrates. Alumina, on the other hand, is significantly more economical, mechanically robust in wear environments, and possesses exceptional electrical breakdown resistance.
Aluminium Titanate features an extremely low thermal expansion coefficient and high thermal shock resistance. Most importantly, molten aluminum and its alloys do not wet or adhere to Aluminium Titanate. This ensures clean liquid metal flow, zero casting inclusions, and years of maintenance-free riser tube life.
