It has great formability and weldability, along with excellent corrosion resistance.

304 Stainless Steel Pipes
Grade 304 stainless steel pipe is the most standard used alloy of stainless steel type.
Essentially, garde 304 is an austenitic chromium alloy which is also known as an “18/8” stainless as the make-up of the steel is 18% chromium and 8% nickel.
The chromium content promotes the material’s considerable resistance to the effects of corrosion and oxidation. The stainless steel alloy resists most oxidizing acids and will withstand ordinary rusting though this does not mean that the steel will not tarnish over time.
Grade 304 stainless steel pipes exhibit good machinability and have excellent weld-ability characteristics with or without the addition of filler metals.

316L Stainless Steel Pipes
316L stainless steel pipe has a wide range of applications in the chemical industry due to its excellent corrosion resistance.
316L is also a derivative of 18-8 type austenitic stainless steel, with 2 to 3% of Mo added.
The Mo content of 316L makes this steel have excellent corrosion resistance and can be safely used in environments containing CI and other halogen ions.

Red Copper Materials
Because of red copper good ductility, high thermal conductivity, electrical conductivity and corrosion resistance, it has become an important engineering material in the field of metal and electrical engineering.
The alloy is a mixture composed of two or more different metals (or one or more metals and non-metals), which has a new type of performance that does not exist in any single metal. Because it can make full use of the beneficial properties of each component, it is often better than pure metal performance.
Therefore, alloys have been widely used in various fields of national economy.

When you choose to buy custom made corona rings and shielding components, there have some important points of materials selection we need to know before we get started.
What Are The Metal Materials Of Corona Rings?
Let us introduce the common polishing and piping bending corona rings aluminum materials.
Since aluminum material is high strength with light weight, our partners can benefit from the material because the corona products made of these are high purity and light for transportation and easily installed.
Good Weldability: Grade 3A21/6061/6063/1060 aluminum material have good weldability for corona rings production process. After the welding process, our Highv workers will set about doing polishing process for aluminum corona rings. As you know, the soft aluminum material is easily for this process. Not only the diameters of corona rings can influence the corona effect, but also the corona rings need to be polished bright to achieve more smooth and no burr surface finish to ensure better corona shielding control effect.
Light Weight: High purity aluminum density is 2.7g/cm3.
This feature is high cost-effective no matter what is for industry production still for the shipment.
Choosing the aluminum material for your corona rings projects can help you save your more time and money.
Corrosion Resistance: Aluminum alloy naturally protects itself by forming a layer of oxide in its surface when in contact with the atmosphere that prevents further corrosion. So this feature can help aluminum corona rings a longer operation life period.
Environmentally Friendly: Aluminum has a very low melting point therefore it can be easily melted and 100% of it can be reused.
The combination of all these amazing properties make aluminum the material of choice for aluminum corona rings and components applications.
Difference Between 6061 Aluminum Material And 6063 Aluminum Material
Many customers are not very clear about 6061 aluminum material and 6063 aluminum material, so they don’t know which one to choose, especially when they need to buy a large amount of aluminum corona rings. So what is the difference between 6061 aluminum material and 6063 aluminum material?
Aluminum alloy is a kind of metal material. According to the composition, it can be divided into pure aluminum, aluminum alloy, aluminum-magnesium alloy, aluminum-magnesium-silicon alloy, aluminum-magnesium-silicon-copper alloy, etc. It has good corrosion resistance and processing performance, easy coating and galvanizing, and has excellent weldability.

Difference Between 6061 Aluminum Material And 6063 Aluminum Material:
1. Different states: The 6061 material is a pre-stretched T6 state. The 6063 material is a T5 state.
2. Different mechanical properties: the mechanical properties of 6061 T6 are significantly better than those of 6063 T5. The tensile strength of 6061 alloy is greater than that of 6063 alloy.
3. Different appearance: The impurity content of the 6061 material is higher than that of the 6063 material.
4. The chemical composition of the two materials is different.

4.3A21 aluminum material can be used in the manufacture of corona rings and other structural parts with high formability requirements for sheet metal parts that are not stressed by heat treatment but require high crack sensitivity.
Why Use Red Copper For Corona Shielding Spheres Production?
Red copper is used to produce corona shielding spheres/balls for wear-resistant, electronics, and electrical appliances.
The reason why red copper is used to produce corona shielding spheres:
1. Red copper has a low content of iron and other non-magnetic elements.
2. The hardness of red copper ball is higher than that of steel ball, which is convenient for producing copper balls with large diameter and high hardness.
3. Red copper is easy to be carburized in the atmosphere, which can be used for the production of ultra-high temperature resistant copper spheres.
