Price wars and low profits, only 20% of the profits of Shenzhen LED companies

With the ebb and flow of LED Red Sea, Shenzhen has recently formed a few industry leading companies, and more small and micro enterprises have gone bankrupt, and there have been phenomena of significant price cuts in LED products. According to industry insiders, the proportion of Shenzhen LED lighting profitable enterprises will not exceed 20.
Due to the high expectations of LED lighting, many companies are involved in the LED industry, and the threshold for the LED industry has been greatly reduced. But at the same time, the influx of large amounts of capital led to overcapacity, and the price war of one month's quotation made LED companies miserable. For example, the price of an ordinary LED fluorescent lamp two years ago was 200 yuan, 150 yuan a year ago, 100 yuan six months ago, and now only 80 yuan, the price is fast.
The influence and scale of Shenzhen's LED industry is second to none in the country. In 2011, the output value of Shenzhen LED enterprises reached 70 billion yuan. In the same period, the industrial output value of Guangdong Province was nearly 150 billion yuan, and Shenzhen accounted for half of the province. At present, there are about 20 LED listed companies in China, and Shenzhen accounts for almost half.

Mixed Powder

Tungsten carbide mixed Metal Alloy Powder is commonly used in PTA (Plasma Transferred Arc) welding. PTA welding is a process that involves the deposition of a hardfacing material onto a base metal to provide wear resistance, corrosion resistance, and improved mechanical properties.

Tungsten carbide is a very hard and wear-resistant material, making it ideal for applications where high abrasion resistance is required. It is often mixed with other metals, such as nickel, cobalt, or chromium, to form a metal alloy powder. These metal alloys enhance the properties of the tungsten carbide and improve its compatibility with the base metal.

The tungsten carbide mix metal alloy powder is typically fed into the PTA welding torch, where it is melted and propelled onto the surface of the base metal using a high-energy plasma arc. The molten powder forms a hard, dense coating that bonds with the base metal, providing excellent wear resistance and protection.

The specific composition of the tungsten carbide mix metal alloy powder can vary depending on the application requirements. Different ratios of tungsten carbide and other metals can be used to achieve desired properties, such as hardness, toughness, and corrosion resistance.

Overall, tungsten carbide mix metal alloy powder is a versatile and effective material for PTA welding, offering superior wear resistance and protection for various industrial applications.
