The difference between aluminum air pipe head and cast iron air pipe head
Aluminum alloy air pipe head and cast iron air pipe head are common types of air pipe head. Aluminum alloy is a very practical material with good strength and corrosion resistance. Cast iron is a kind of material of iron-carbon alloy, because of its cheap price and stable performance, it is widely used in various mechanical parts and components. In addition, there are many differences in materials and properties.
Overview
Materials
Aluminum: Aluminum alloy is a non-ferrous metal alloy composed of aluminum, copper, magnesium, manganese and other elements. Aluminum alloy has the characteristics of light weight, high strength, good thermal conductivity and corrosion resistance.
Cast iron: Cast iron is a general term for an alloy composed mainly of iron, carbon and silicon. Cast iron has the characteristics of high strength, good corrosion resistance, strong processability and low cost.
Strength
Aluminum: The strength of aluminum alloy air pipe heads is usually higher than that of cast iron air pipe heads, and it performs better in practical applications.
Cast iron: The strength and toughness of cast iron air pipe head is generally not higher than that of aluminum alloy air pipe head. However, the performance of cast iron can still meet the demand in practical applications.
Corrosion Resistance
Aluminum: Aluminum alloy is a material with excellent corrosion resistance, and no additional anti-corrosion treatment is required for the aluminum alloy air pipe head during normal use.
Cast iron: Cast iron is also a common material, although its corrosion resistance is not as good as aluminum alloy, but also has a certain ability to resist oxidative corrosion. However, the cast iron air pipe head is more susceptible to corrosion during long-term use and requires external anti-corrosion treatment.
Cost
Aluminum: Compared with cast iron, the price of aluminum alloy is higher. Therefore, aluminum alloy air pipe heads are usually more expensive than cast iron air pipe heads.
Cast iron: The price of cast iron is lower than aluminum alloy, so the cost of cast iron air pipe head is lower.
