ZHKL Metal Ceramic Materials Technology Co., Ltd.
Products mainly include Metal-based ceramic composite materials: silicon carbide particle reinforced aluminum matrix composite materials, silicon aluminum composite materials and precision parts.
It is one of the very few enterprises in China that possesses silicon carbide particle reinforced aluminum matrix composite materials, silicon aluminum composite materials ultra-high precision complex parts manufacturing technology. The high-precision processing of the aluminum-based ceramic composite material is realized and the processing cost can be effectively controlled.
The company is the supporting unit of China Silicon Carbide Particle Reinforced Aluminum Matrix Composites, silicon aluminum composite materials engineering technology research center. Since 2009, the company has undertaken 8 national projects and 6 provincial and ministerial projects. It has 5 national invention patents and 25 national utility model patents.
In the field of metal-ceramic composite materials, the company's product research and development will meet the quality standards of metal-ceramic composite materials of Lockheed Martin of the United States and Kyocera of Japan.
The metal-based ceramic composites developed by SZKL and aluminum-based composites have comprehensive advantages such as high thermal conductivity, low density, and low cost. They are an important category of metal-based materials, and have been widely researched and applied in industrial production in the international and domestic areas. Aluminum-based composite materials include fiber reinforced and particle reinforced. Among them, particle-reinforced aluminum matrix composites have low cost, stable performance, and are easy to achieve large-scale production, which has become a hot spot in the research and application of aluminum matrix composites. Composite materials based on aluminum alloys include aluminum silicon carbide and silicon aluminum, which are widely used in aerospace, electronic information, housing packaging and modern transportation.
The aluminum silicon carbide and silicon aluminum metal-based ceramic composite materials developed by the company have been introduced into the body, reflectors, concave plates and other products, and have been successfully applied to China's aviation, aerospace and military industries.
Representative products:
1. Metal-based ceramic composite material navigation platform
Application areas: inertial navigation equipment for aircraft and ships;
Alternative material: aluminum alloy;
Alternative advantages: The thermal stability is three times that of aluminum alloy, and the amount of deformation under mechanical load is only one third of that of aluminum alloy, which is not prone to resonance. The modal frequency is increased from 1400Hz to above 2000Hz, which is less prone to resonance phenomenon, which effectively guarantees the inertial navigation accuracy of the equipment.
2. Metal-based ceramic composite glass mirror silver ink reflector
Application field: Reference mirror (100mm caliber);
Index: Ra0.005, flat crystal detection of an aperture, the reflectivity in the mid-to-far infrared band is greater than 85%;
Alternative materials: aluminum alloy-dispensing-ceramic / glass reflection system;
Alternative advantages: The entire system is replaced with a functional material, which avoids the reference offset caused by the aging of the colloid, effectively avoids the problems of recalibration and reassembly, and reduces the maintenance cost by 80%.
