Aluminium shims are a minor but very important aspect in contemporary industrial activity. Aluminium shims find extensive applications in heavy engineering and construction, aerospace and marine equipment in providing very accurate alignment, spacing and loading distributions. They are lightweight, corrosion resistant, and versatile, and this has made them the choice in various industries where accuracy and reliability are very important.
When a company is in need of precision components, a reputable Aluminium Shims Manufacturer in India provides a stable quality and availability of various alloys as well as reliable technical services.
What Are Aluminium Shims
Aluminium Shims are fine sheets or strips of aluminium produced at specific thicknesses. They are applied to fill in any gaps, to adjust any misalignment, to level machinery, and to provide a good fit between parts. Shims are used to offset tolerances in the manufacturing and installation process and promote smooth functioning, as well as to minimize the mechanical stress.
Aluminium shims have different thickness, which can be cut or fabricated to suit the needs of a size. Their flexibility also allows them to be used in services that are permanent as well as temporary during maintenance or assembly.
Why Aluminium Is Used for Shims
There are a number of benefits that aluminium has compared to other shim materials like steel or plastic. Its lightweight nature is one of the main advantages in that it does not affect the overall structural load, but it does not affect the performance. Aluminium is also highly resistant to corrosion and hence can be used at humid, marine as well as chemically exposed environments.
Moreover, aluminium is machinable, cuttable, and formable which means that it can be modified in place very fast. Its non-magnetic and conductive characteristics also give it an extended application in electrical and electronic equipment. Its high adoption is also due to the cost-effectiveness and its availability in various grades.
Industrial Benefits of Aluminium Shims
The aluminium shims are used to enhance accuracy of the equipment, minimise vibration, as well as, increase the load distribution. Proper shimming reduces the wear on components, prolongs the life of equipment and minimizes downtime due to misalignment or uneven distribution of the load.
They also give flexibility in installation enabling the engineers to adjust positioning without remachining parts. Aluminium shims are used in a big-scale industrial project to ensure accelerated construction process, enhanced safety, and stability in operation.
Aluminium 7075 Shims
Aluminium 7075 shims are characterized by the high strength and hardness. The grade has one of the best strength to weight ratios of the aluminium alloys and is thus applicable in tough applications.
Aluminium 7075 shim finds a lot of application in aerospace, defence and high-performance engineering where structural integrity and fatigue resistance are paramount. These shims have relatively reduced corrosion resistance, and so, they are commonly employed in controlled environments or under protective surface treatment.
Aluminium 7050 Shims
The aluminium 7050 shims have applications in which the shims are needed to be very strong but with a better corrosion environment than that of 7075. This grade has a high degree of performance at high stress levels and at different temperatures.
The most common use is aircraft structures, heavy load-bearing assemblies, and other critical engineering components. Aluminium 7050 shims have been appreciated due to their stability in terms of dimensions and long term usage.
