The strategic cooperation between the Guangxi Zhuang Autonomous Region Government and the Nanning Municipal Government and China South Locomotive has taken substantial steps. On July 17, the opening ceremony of the Nanning Nanche Aluminum Precision Machining Project was held in Nanning.

With CSR Zhuzhou Electric Locomotive Co., Ltd. and Guangxi Nannan Aluminium Processing Co., Ltd. engaged in Nanning in technology, capital, and projects, from ore to aluminum ingots, from aluminum ingots to profiles, and then from profiles to a modern metro With the production of relevant products such as carriages, Zhuangxiang’s aluminum precision machining will be on the fast track, and Guangxi’s aluminum industry chain will be further enriched. CSR ZLC’s successful expansion of the market for proprietary technology extension products in the urban rail industry is also expected. Zhuangxiang and CSR will achieve a strategic win-win situation.

In July 2010, CSR and the Guangxi Zhuang Autonomous Region People's Government signed a strategic cooperation framework agreement. In December 2011, CSR and the Nanning Municipal People's Government signed a strategic cooperation framework agreement in Nanning. According to the framework agreement, the two parties will join hands on rail transit. Strategic emerging industries such as equipment and new energy vehicles, and cooperation in aluminum precision machining, stainless steel sheet and key parts and components for rail transit equipment parts.

As an important part of the framework agreement, in December 2011, CSR Zhuzhou Machinery Co., Ltd. and Guangxi Nannan Aluminum Processing Co., Ltd. formally signed a joint venture agreement for the fine processing of aluminum materials. Both parties jointly established Nanning Nanche Aluminum Precision Processing Co., Ltd. This foundation-launching project is located in the production park of Guangxi Nannan Aluminium Processing Co., Ltd., and the first phase investment will be approximately RMB 120 million.

The business scope of Nanning CSR Aluminum Precision Machining Co., Ltd. includes: aluminum profile processing, aluminum construction floors for subway vehicles, air conditioning panels, and pantograph plate welding processing, metro vehicle roof attachments, partition walls, underframe accessories, body accessories , Machinery and other small parts of the wall cutting and processing. After the implementation of this project, it can form an annual production capacity of 150 precision aluminum rail supporting products for urban rail vehicles.

CSR ZLC is a leading enterprise of rail transit equipment manufacturing in China and has the advantages of technology, management, and products in the field of rail transportation equipment. In recent years, with the rapid development of its rail transportation equipment industry, the demand for high-quality aluminum materials has continued to grow. Increase.

Guangxi, which is rich in aluminum resources, is one of the major aluminum bases in China. Guangxi Nannan Aluminum Processing Co., Ltd. has strong aluminum processing capacity. The capital city of Nanning is adjacent to Guangdong, Hong Kong and Macao, backed by the Southwest, faces the Beibu Gulf, and radiates Southeast Asia. The geographical advantage of Chengdong Qixi and Liannan is the overlapping of regional economic cooperation in the China-ASEAN Free Trade Area, the Greater Mekong Subregion, the Pan-Beibu Gulf Economic Zone, and the pan-Pearl River Delta regional economic cooperation. The core of the meeting point. The resources advantages and regional radiation advantages here have attracted CSR from China.

Xu Zongxiang, executive director and general manager of CSR Zhuzhou Machinery Co., Ltd. of China, said that both sides have carried out industrial extensions and cooperated in the field of aluminum precision machining to develop and develop precision aluminum products for rail transit, which can achieve complementary advantages and achieve a win-win situation. With the regional advantage of aluminum precision machining projects, this base will become another bridgehead for CSR Zhuzhou Machinery Co., Ltd. to enter the ASEAN market.

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.  As the name suggests, a permanent magnet is 'permanent'. This means that it always has a magnetic field and will display a magnetic behavior at all times.

A permanent magnet`s magnetic properties exist when the magnet is (magnetized). An electromagnetic magnet only displays magnetic properties when an electric current is applied to it. That is how you can differentiate between the two. The magnets that you have affixed to your refrigerator are Permanent Magnets, while electromagnets are the principle behind AC motors.

Permanent Magnet v. Electromagnet: Magnetic Strength
Permanent magnet strength depends upon the material used in its creation. The strength of an electromagnet can be adjusted by the amount of electric current allowed to flow into it. As a result, the same electromagnet can be adjusted for different strength levels.

Permanent Magnet v. Electromagnet: Loss of Magnetic Properties
If a permanent magnet loses its magnetic properties, as it does by heating to a (maximum) temperature, it will be rendered useless and its magnetic properties can be only recovered by re-magnetizing. Contrarily, an electromagnet loses its magnetic power every time an electric current is removed and becomes magnetic once again when the electric field is introduced.

Permanent Magnet v. Electromagnet: Advantages

The main advantage of a permanent magnet over an electromagnet is that a permanent magnet does not require a continuous supply of electrical energy to maintain its magnetic field. However, an electromagnet`s magnetic field can be rapidly manipulated over a wide range by controlling the amount of electric current supplied to the electromagnet.

A permanent magnet retains its magnetic properties for a long time.
A lodestone is a naturally occurring permanent magnet composed of magnetite, an iron-bearing mineral. Such magnets have been known since ancient times. Virtually all magnets used commercially today are made from synthetic magnetic materials. The most common such materials are alnicos-iron alloys containing aluminum, nickel, and cobalt. Magnetic materials containing such rare-earth elements as samarium or neodymium form very strong permanent magnets. Ferrites, which consist of ferric oxide (an oxide of iron) combined with the oxides of one or more other metals, are widely used in electronic devices. Flexible magnets are made by combining magnetic materials with plastics.
Permanent magnets are typically made into U-shaped horseshoe magnets, with the poles side by side; and bar magnets, with the poles at opposite ends.
