While a normal sheet of aluminum can be easily cut with the help of a table saw and blade, cutting aluminum diamond plate is relatively intricate because of the pattern.
It can be cut on a table saw or with a circular saw with a good carbide tipped blade (the more teeth the better), or better yet, one like Mike linked to that is designed for non-ferrous metals.
Mount a diamond blade in your angle grinder and use it like a saw to cut the mesh. We recommend using a diamond blade that’s labeled as a ferrous-metal-cutting blade, but many tradespeople use a regular masonry diamond blade with good results.
You can cut thin ( one eighth or less) aluminum with just about any wood cutting blade.
Can you cut aluminium with a plasma cutter? Yes, as with any electrically conductive metal, plasma cutting aluminium is not just possible, it is highly effective.
Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.
The plasma cutting process may be used to cut any conductive material, including carbon steels, stainless steels, aluminum, copper, brass, cast metals, and exotic alloys.
Aluminum falls into the category of being a conductive metal and, therefore, is easily cut by a plasma cutter if it’s less than six inches thick. Plasma cutters can cut through most conductive metals, but it becomes harder the thicker the metal is.
Plasma cutters are used to perform cutting and gouging operations, with the average hand-held system capable of cutting a maximum metal thickness of about 1 inch.
Virtually any metal can be plasma cut including steel, stainless steel, aluminum, brass, copper, etc. Any thickness from 30 gauge through 1 inch can be cut, depending on the plasma cutter used. Plastics and wood are not electrically conductive and cannot be plasma cut.
Oxygen. Oxygen has become the industry standard for cutting mild steel because it provides the best, clean cut quality and fastest cutting speed of any plasma gas. (Plasma cutting aluminum plate or stainless plate with oxygen plasma gas is not recommended).
Gas is needed for a plasma cutter in order for it to work and create the plasma. As mentioned, the most popular gases to use are oxygen, nitrogen or argon. Different gases are used depending on the type of metal you are cutting.
Argon-Hydrogen is required for mechanized cutting of any material more than 3 inches thick. This mixture also provides an excellent gas for plasma gouging on all materials.
Argon gas is used when plasma marking (a whole other subject). A mixture of Argon and Hydrogen is often used when cutting thicker Stainless Steel or Aluminum. Some people use a mixture of Hydrogen and Nitrogen, or Methane and Nitrogen when cutting thinner Stainless Steel.
Laser cutting is a precise thermal cutting process, utilizing a focused beam of light. Plasma cutting, on the other hand, uses a mixture of gases in order to form a cut. With our high definition plasma cutting equipment, we are able to perform bevel cuts on parts as required.
Do you need a welding mask for plasma cutting? Technically, no, you do not. Many people tend to wear goggles when it comes to plasma cutting or even safety glasses that darken. However, if the torch you are using has enough amps to it, then a welding mask would be ideal for safety reasons.
