On March 28, 2023, China’s high-performance ultra-thin stainless steel foil manufacturer: TGJT announced:
The ultra thin nickel based alloy strip steel developed by the company has completed small-scale continuous production of dozens of tons, and the product quality meets customer requirements, achieving bulk supply to leading enterprises in lead frame production.
Semiconductor lead frames, as chip carriers for integrated circuits, are important foundational materials in the electronic information industry. With the development of artificial intelligence technology, semiconductor chips, as the core “brain” of the intelligent era, have seen a significant explosive growth in demand for lead frames.
Nickel based precision alloy strip with a thickness of 0.1-0.4 millimeters has excellent magnetic, electrical, processing and welding properties, making it an excellent material for lead frames.

However, currently there are problems with insufficient supply, long supply cycles, and high prices of imported materials, which seriously restrict the development of China’s electronic information industry.
TGJT conducts technical research and development in areas such as alloy purity, coefficient of thermal expansion, and surface quality control. After multiple rounds of full process trial production, precise production organization, and process improvement targeting more than 10 core technical parameter requirements of customers, precision alloy strip steel has finally been developed.
TGJT has successfully developed an advanced process for producing nickel based precision alloys based on ultra precision stainless steel foil production lines, overcoming the shortcomings of small furnace loading and poor product quality stability of similar products in China. It has the ability to produce high-quality and large-scale products, meeting the needs of international first-class lead frame users.
