Tool plate, sometimes called tool and jig plate, is one of the precision options in cast aluminium. With the specialized production methods, the best cast aluminium tool plate is produced without any internal stresses.
The benefits to the using this material include a highly stable aluminium plate that will have only a very limited internal movement during machining. With this in place, it is possible to machine the cast aluminium tool plate to high tolerances that are not possible with other types of aluminium plate.
The 5083 Alloy
There are different alloys that can be used for the production of cast aluminium tool and jig plate. The most commonly selected alloys the 5083. This is an alloy that offers durability even in very extreme use environments. It is most often the alloy used when there is exposure to seawater or industrial chemicals.
The chemical composition of 5083 aluminium alloy includes magnesium, manganese, iron, silicon, zinc, copper, and titanium. There is also a lower amount of chromium. This is considered an excellent choice of an alloy to use in welding due to the retention of strength. It can be welded using WIG/MIG welding as well as resistance welding operations.
The Tool Plate
As mentioned above, this cast aluminium tool plate has minimal distortion even after machining. It is also a plate that can be produced with very flat surfaces on both sides. Precision milling and precision sawing create an ideal surface area and edge, providing the best material possible for precision parts and components.
One other reason for using 5083 aluminium tool plate over steel plate in many applications is the dramatic reduction in weight. The aluminium plate is much easier to move and work with, offering the same durability and strength at about one-third of the weight of a similar plate made of steel.
