One of the patents of Vanse industrial ceiling fans is the variable-section streamlined fan blade,which uses a 1.5 mm thick 5052 high-grade high-density aluminum alloy mother plate used in the aviation industry.Because of its high strength and flexibility,the middle of the Vanse industrial ceiling fan blade is There is no need for reinforcing ribs,thereby reducing the weight of the fan blades and lowering the energy consumption of the fan.Most of the industrial ceiling fans on the market use low-grade aluminum or mixed with recycled aluminum for secondary processing,which has low density,impurities,pores,low strength and easy fracture.

For many customers who do not understand the difference between various aluminum alloys,Vanse introduces the properties of various aluminum alloys here.There are 9 series of aluminum alloys from 1 to 9:

One series: 1000 series aluminum alloys represent 1050,1060,1100,and do not contain other technical elements,so the production process is relatively simple and the price is relatively cheap.It is the most commonly used series in conventional industries.

Second series: 2000 series aluminum alloys represent 2024,2A16 (LY16),2A02 (LY6).The 2000 series aluminum plate is characterized by high hardness,among which the original copper content is the highest,about 3-5%.2000 series aluminum rods belong to aviation aluminum materials,which are not often used in conventional industries.

Three series: 3000 series aluminum alloy represents 3003,3A21 mainly.my country's 3000 series aluminum plate production technology is relatively good.The 3000 series aluminum rod is mainly composed of manganese element,and the content is between 1.0-1.5.It is a series with good anti-rust function.

Four series: 4000 series aluminum rods are represented by 4A01,4000,which belong to the series with high silicon content,usually between 4.5-6.0% silicon content,which are building materials,mechanical parts,forging materials,welding materials,low melting point,Good corrosion resistance.

Five series: 5000 series aluminum alloy represents 5052,5005,5083,5A05 series.5000 series aluminum rods belong to the more commonly used series of alloy aluminum plates.The main element is magnesium,and the magnesium content is between 3-5%.It can also be called aluminum-magnesium alloy.The main features are low density,high tensile strength and high elongation.Under the same area,the weight of aluminum-magnesium alloy is lower than that of other series,and it is also widely used in conventional industries.

Six series: 6000 series aluminum alloy represents 6061,which mainly contains two elements of magnesium and silicon,so it concentrates the advantages of 4000 series and 5000 series.6061 is a cold-treated aluminum forging product,which is suitable for applications with high requirements for corrosion resistance and oxidation resistance..Good workability,easy to coat,and good workability.

Seven series: 7000 series aluminum alloy represents 7075,mainly contains zinc element,also belongs to aviation series,is aluminum magnesium zinc copper alloy,is heat treatable alloy,belongs to super hard aluminum alloy,has good wear resistance.At present,it basically relies on imports,and my country's production technology needs to be improved.
Eight series: 8000 series aluminum alloys are more commonly used 8011,which belong to other series,most of which are used for aluminum foil,and are not commonly used in the production of aluminum rods.

Nine series: 9000 series aluminum alloys are backup alloys.

At present,most industrial large fans on the market are made of aluminum alloys of three series and four series,because of their cheap price and bright appearance,but from a safety point of view,although the hardness of three or four series aluminum alloys can meet the requirements,the toughness is insufficient.It is very easy to break if it collides with items during operation.In consideration of safety,our company has upgraded the product.The 5 series aluminum alloy used in large equipment such as aircraft and ships is used.Its tensile strength and elongation are high,and it will not break even if it is collided.Corrosive,with ultra-high performance guarantee.
