In Air conditioner, coils are used to convert gas refrigerant to liquid refrigerant and vice versa, which is used to further cool the room. However, copper coil or aluminium coil does the same job, but there are certain difference in their heat transmission capability, durability and resistant to corrosion. Here we are presenting our review on which is best among the copper and aluminium coils. Try our Air Conditioner selector to choose right air conditioner by answering simple questions without reading any buying guide.
The embossing technique consists in printing on a smooth surface that produces a relief pattern. The embossed aluminum coil is obtained with the hot meltingof the raw material, cold rolling and surface treatment, and finally cutting and embossing, according to the uses.
HVAC coils are often made with copper and aluminum, two metals that efficiently transfer heat. That’s because cost and effective heat transfer are often the key deciding factors in choosing materials for HVAC coils. There are pros and cons to both copper and aluminum, which I describe below.
Aluminum is actually a very active metal, in the sense that it oxidizes very quickly. This feature, while a weakness for most metals, is actually the key to its ability to resist corrosion. When oxygen is present (in the air, soil, or water), aluminum instantly reacts to form aluminum oxide. This aluminum oxide layer is chemically bound to the surface, and it seals the core aluminum from any further reaction. This is quite different from oxidation (corrosion) in steel or other metals, where rust puffs up and flakes off, constantly exposing new metal to corrosion. Aluminum’s oxide film is tenacious, hard, and instantly self-renewing.
The color-coated aluminum sheet coil is ideal for producing aluminium composite materials. haomei aluminium coil is coated with high quality fluororesin paint which offers good weather resistance.
Stucco embossed aluminum sheet has many pattern, orange peel pattern is the most common seen type. Orange peel stucco embossed aluminum sheet has classic orange peel pattern and variation orange peel pattern which also known as insect pattern. Orange peel stucco aluminum sheet is the ideal material for used in refrigerators, air conditioners and packaging.
The 5182 aluminum coil belongs to Al-Mg-Si series alloy and has a wide range of applications. It is commonly used in automotive parts, can tab and can end. 5182 aluminum coil has good corrosion resistance, excellent weldability, good cold workability, and moderate strength. The main alloying element of 5182 aluminum alloy sheet is magnesium, and a small amount of silicon is added. Therefore, the welding performance of welding 5182 aluminum plate using gas welding, argon arc welding, spot welding and seam welding is very good.
The coated aluminum coil is ideal for producing aluminium composite materials. Aluwell aluminium coil is coated with high quality fluororesin paint which offers good weather resistance.
Color coated Aluminum Coil is the most popular new material currently. It is especially suitable for interior decoration and AD boards. color Coated Aluminum Coil refers to the aluminum coil through coating and coloring treatment generally includes PE coated aluminum coil and PVDF coated aluminum coil.
Many sheet metal manufacturers produce aluminum trim coil that you can install on your house to cover base materials to provide a finishing feature. Typical uses include the trim for windows, soffit boarding, siding and roof edging. Aluminum trim coil comes in a large range of colors, widths and gauge thicknesses to complement your trim design needs. Knowing how to install the trim allows you to create a professional finish that is durable and cost-effective over the long term.
Aluminum strips refers to further processed products of aluminum coil. As important raw material in many industries, they can be divided into eight series, among which only four are the most widely applied: 1000 series, 3000 series, 5000 series and 8000 series. In accordance to different temper states, aluminum strips are classified into three types: O state, H24 state and H18 state. O stands for the softest state. H24 stands for half hard state and H18 hard state. Owing to the fact that most aluminum strips need to be bent or twined, O state proves to be the most popular one.
