What are the materials of corona rings? It depends on corona rings design and manufacturing process.
The custom aluminum corona rings are usually made from 6061 thin wall tubing or pipe that is formed and welded; with appropriate supporting brackets and other mounting standards.
In some conditions, the stainless steel materials will be used.
Aluminum alloy is a popular metal material to use for corona rings production.
Because it is both cost effective and high weather resistance.
The soft hardness is easily processing and polishing.
Die casting rings materials are usually A380 and ZL101.
ZL101 die casting aluminum alloy can be strengthened by heat treatment, which has natural aging ability, high strength and good plasticity.
ZL101 die casting aluminum alloy has excellent casting properties, good fluidity, small linear shrinkage, low thermal cracking tendency and high air tightness. But it has a slight tendency to produce porosity and shrinkage.
This alloy has high corrosion resistance, good weldability and general machinability.
A380 type die casting aluminum alloy is the most common special aluminum alloy because it integrates the characteristics of easy casting, easy machining, and good heat conduction.
It has strong mobility, pressure bearing, and high temperature resistance.
Although the A380 type alloy has always been considered convenient for machining, it is slightly rough due to its higher silicon content.
It is widely used in various products, including chassis of electrical equipment, engine brackets, gearboxes, furniture, generators and hand tools, etc.
Of course, it is also the material of the aluminum die casting corona ring.
Stainless steel is the kind of material which is not easy rust, acid resistance and corrosion resistance, so it is widely used in light industry and heavy industry.
Sometimes end users need some special corona rings made of stainless steel for outdoor applications.
Grade 201 reduces corona rings producing cost, increases mechanical strength and makes grade 201 work harden at a faster rate than grade 304 stainless steel material.
Grade 304 stainless steel material is a smart choice for your stainless steel corona rings project and longevity. It is cost-effective in comparison to other stainless steel materials.
Grade 304 material’s high quality and durability ensures that your product lasts a long time and the production of it is suitable for almost industry use.
Grade 316 stainless steel material, is a popular grade of stainless steel where superior corrosion resistance is of primary importance.
Grade 316 stainless steel corna ring is used for outdoor high voltage applications.
