In 2025, the industrial manufacturing sector is facing an unprecedented challenge in terms of raw materials.   Due to the combined effects of environmental protection production restrictions, tightened mining quotas (with tungsten ore quotas expected to decrease by approximately 6.45% in 2025 compared to the previous year), and the growth in downstream demand from sectors such as photovoltaics and military industry, the price of tungsten concentrate has risen by nearly 80% this year, reaching a new high in the past decade. Meanwhile, the export restrictions on tungsten-related products have become stricter, putting pressure on enterprises that rely on tungsten steel (hard alloy) for manufacturing tools, wear-resistant parts, and molds, as they are confronted with both cost and supply issues.   Against the backdrop of continuous price hikes of tungsten steel and increasing supply uncertainties, finding mature and reliable alternative materials for tungsten steel has become an u...

In a vacuum environment, the pivotal conduit for secure energy transmission.  Vacuum electrical power feedthrough is a key through component specially designed for vacuum systems. Its core function is to safely and reliably transfer electrical energy from the atmospheric environment to the vacuum interior while absolutely maintaining the vacuum seal of the cavity. It is the indispensable “energy link” that connects the external power source with the internal load of the cavity.   This component has solved the core problem of stable power supply under high vacuum conditions, and is the foundation for the reliable operation of various heating, high-voltage, and particle beam processes.     Design core: Sealing, insulation and current carrying capacity   The design of vacuum electrical power feedthrough is centered around three core aspects: sealing, insulation, and current-carrying capacity.   (1) Based on the mature ceramic-metal brazing technology, an atomi...

  High-temperature zirconia materials, due to their comprehensive “thermal shock resistance,” “corrosion resistance,” “high-temperature strength” and “erosion resistance,” have become key materials for ensuring the safe, efficient, and continuous operation of modern steel continuous casting processes. In particular, their application in core components such as continuous casting nozzles, which control the flow of high-temperature melt, brings benefits such as improved production stability, reduced accident rates, and improved product quality.   Below are some product examples:   1.Sizing Nozzle: A sizing nozzle is a high-temperature structural ceramic functional device installed at the bottom of the continuous casting tundish. Its main function is to maintain a relatively constant static pressure of molten steel in the tundish. Molten steel flows into the crystallizer via the sizing nozzle. The crystallizer uses high-flow-rate water cooling to remove the heat released dur...
