Relationship between fin stock and air conditioner

At present, the fin stock for air-conditioning heat exchange sheets can be mainly divided into two types: non-coated fin stock (sugar foil) and coated fin stock. Non-coated fin stock refers to the stock of fins that are annealed by rolling and have not been subjected to any treatment on the surface; coated fin stock refers…

Fin stock manufacturer and supplier China

The traditional view is that casting and rolling blanks are not suitable for use as fin stock products. The main reason is that when the cast billet is used to produce fin stock, the plasticity is insufficient and the hardening speed is fast, resulting in poor deep-drawing performance of the fin stock. However, in recent…

Talking about the development of fin stock

The fin stock is a special material for manufacturing heat exchanger fins for air conditioners, and the fin stocks used in the early days are plain foils. In order to improve the surface properties of the plain foil, an anti-corrosive inorganic coating and a hydrophilic organic coating are applied before forming to form a hydrophilic…

Advantages of Hydrophilic Fin Stock

It is understood that the coating fin stock mainly include hydrophilic fin stock, water-repellent fin stock and other varieties. At present, the basic use of fin stock is: inverter air conditioners, high-end models, export outlet air conditioners mostly use hydrophilic fin stock; domestic air conditioners, window machines, car air conditioners mostly use plain foil. Currently,…

Fin stock for air conditioning heat exchanger

Fin stock: The large-scale use of fin stocks for the production of air-conditioning heat exchangers has a history of more than 20 years in China, and has been developed at a high speed in the past 10 years. With the development of China’s economy and the continuous improvement of people’s living standards, the popularity of…

Seven categories of fin stock

According to its processing technology and performance characteristics, fin stock can be divided into 7 categories: 1. Non-coated fin stock. Non-coated fin stock refers to aluminum foil that has been subjected to rolling annealing without any surface treatment. In China 10 years ago, the aluminum foil used for air conditioning heat exchange sheets about 15…

Fin stock market is highly competitive

The price of aluminum foil is generally the price of aluminum ingots plus processing fees. Air-conditioning companies generally determine the fin stock suppliers by tender at the beginning of the freezing year. The price of aluminum ingots is generally the average value of aluminum ingots on the Shanghai Stock Exchange one month before delivery. Therefore,…

Fin stock composite foil or into a trend

Since the manufacture of a thin fin stock can not only reduce the amount of aluminum used in the same heat exchange area, but also reduce the cost of the air conditioner radiator. Therefore, reducing the thickness of aluminum foil has been the development trend of fin stock products and the magic weapon. With the…

Main technical indicators of coated fin stock

The coated fin stock is formed by surface treatment on the basis of the non-coated fin stock, in addition to the chemical composition, mechanical properties and geometric dimensions required for the above non-coated fin stock, it should also be Good board and coating properties. 1 aluminum foil plate type First, the production process for coated…

Anti-corrosion measures for fin stock

Common alloys for fin stock are 1100 aluminum foil, 3003 aluminum foil, 8011 aluminum foil, common state O, H22, H24, H26, thickness range 0.09-0.2mm, width range 100-1300mm. The fin stock has the advantages of low density, good thermal conductivity, easy processing, odorless, environmental protection and low price, just meeting the material selection criteria of the…
