Recently, the Lingyun Auto Parts Project invested by Lingyun Industrial Co., Ltd., a listed company controlled by China North Industries Group Corporation, has signed and settled in the Yantai Development Zone. The project is mainly for Shanghai GM Dongyue base supporting car bumpers, door frames and other components.


The Lingyun Project is just one of the key pieces of the 100 billion-class auto industry in Yantai. While expanding the intermediate manufacturing process, Yantai Development Zone will focus on nurturing the R&D chain, strengthening the marketing chain, increasing global competitiveness, and promoting the development of the automotive industry toward both ends of the “smile curve”. This year, five Fortune 500 companies, including Shougang Toyota Auto Air Conditioner Compressor, Pohang Auster Automotive Chassis, and Yanfeng Biou Automotive Exterior Parts, have joined the Yantai automotive industry, of which two are engaged in R&D and sales.


“The current manufacturing industry has low profits and global manufacturing has oversupply, but R&D and marketing have high added value. We aim at the world’s top 500 to take the initiative and strive to extend the 'smile curve' and reverse the passive situation of using foreign capital.” Yantai Development Zone Business According to Director Zhang Wenqing, a total of 12 automobile investment projects were introduced this year with a total investment of 500 million U.S. dollars.


“The Lingyun Automobile Project's settlement will not only inject the world's top 500 fresh blood into the automobile accessory industry, but will also give full play to the advantages of industrial agglomeration, further optimize the Yantai automobile manufacturing industry structure, and enhance the overall level of industrial development.” Yantai City Economic and Information Commission According to the person in charge, since Shanghai GM Dongyue Base was put into production in 2003, it has cumulatively produced more than 1.7 million cars, more than 5.4 million engines and transmissions.


Up to now, only the Yantai Development Zone has reached more than 200 automotive and component projects, with a total investment of US$3.3 billion, forming an automobile industry system with the entire vehicle as the leader, engines, automatic transmissions, and vehicle air conditioners as the core.



Nickel Based Alloy Powder

Nickel-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent corrosion resistance, high temperature strength, and good weldability. These alloys are typically composed of nickel as the base metal, with various alloying elements added to enhance specific properties.

Some commonly used nickel-based alloy powders for PTAW include:

1. Inconel 625: This alloy powder is widely used for PTAW due to its high strength, excellent resistance to corrosion, and oxidation at elevated temperatures. It is commonly used in applications involving seawater, chemical processing, and aerospace industries.

2. Hastelloy X: This alloy powder is known for its high-temperature strength and oxidation resistance. It is commonly used in applications involving gas turbine engines, industrial furnace components, and chemical processing.

3. Monel 400: This alloy powder is known for its excellent resistance to corrosion, particularly in marine environments. It is commonly used in applications involving seawater, chemical processing, and oil refining.

4. Inconel 718: This alloy powder is known for its high strength, excellent resistance to corrosion, and good weldability. It is commonly used in applications involving aerospace, oil and gas, and nuclear industries.

5. Inconel 601: This alloy powder is known for its excellent resistance to high-temperature oxidation and corrosion. It is commonly used in applications involving heat treatment equipment, chemical processing, and power generation.

These nickel-based alloy powders can be used in PTAW processes to create high-quality welds with excellent mechanical properties and resistance to corrosion and high temperatures.
