Introduction
When my client Bharat Steel, based out of Delhi, approached me last year, their requirement was that of lightweight chassis panels for a new EV prototype. They had tested generic aluminium sheets—only the warping and corrosion came up after weeks of field testing in humid conditions. That was the time I recommended Aluminum Alloy Sheets with BIS Certification under IS 737:2008. The result was very satisfying: no corrosion with up to six months of exposure, 25% weight reduction, and a snug finish for welding. That brought forth such an example to demonstrate that downstream problems can be prevented by the correct choice of material, thereby saving time and cost.
What Are Aluminium Alloy Sheets?
Aluminum alloy sheets became among the most important engineering materials, not just for its lightweight, but because of its outstanding corrosion resistance and excellent mechanical strength. With these properties, aluminum has found a lot of ground in various industrial applications such as automobile manufacture, aerospace, construction, packaging, general engineering, and many others. Its lightweight property reduces the total weight in structures, leading to higher efficiencies and energy savings. With its corroding-resistant properties, aluminum can also provide long service and durability even under harsh environmental conditions.
The other great facilitator that sets standards for the Indian Standards for the quality and performance of aluminum products is IS 737:2008. It has specifications for BIS Certification of wrought aluminum and aluminum alloy sheets and strips designed for the general engineering sector. The specification includes important parameters such as chemical composition, mechanical and other properties, and dimensions-tolerances and surface finishes for general engineering applications. In this way, the products of manufacturers can comply with the overall safety, reliability, and quality checks in place.
These Standards have a great impact on industries. In fact, it has provided consistency and uniformity in the production of BIS Certification for aluminum materials as much as it has boosted the confidence of end-users in the reliability of the product. Therefore, the “quality hygiene” being targeted by industrialization means that the industry lives up to standards at all times to minimize defects and enhance overall end-product performance. Thus, IS 737:2008 becomes a step further in the advancement of engineering practices and builds confidence in the usage of aluminum in different applications.
IS 737:2008 – Quality Assurance for Aluminum & Alloy Sheets
IS-737:2008 has been established by BIS and provides guidelines for the manufacture and quality assurance of wrought aluminum and aluminum alloy sheets and strips. Among the prerequisites of the standard are specifications concerning the chemical composition, mechanical properties, dimensional tolerances, and testing, which ensures that the products fulfill all the imperatives of industry.
Key Features of IS-737:2008
- Chemical Composition The standard limits the permissible incidence of alloying elements such as silicon, magnesium, copper, manganese, and zinc. These elements affect the mechanical strength of the materials, corrosion resistance, and machinability of products. Chemical composition is significant in achieving desired properties and ensuring product reliability.
- Mechanical properties such as tensile strength, yield strength, and elongation are defined by IS 737:2008. These parameters are important to determine the capacity of the material to withstand stress and loads and find application in many engineering fields. Testing has to be employed by compliance to these benchmarks for satisfactory products.
- Dimensional Accuracy and Tolerances The dimensions are the thickness, width, and length of the Alloy sheets and strips, which are described in the standard about acceptable tolerances. This means that adherence to these dimensions guarantees compatibility with other engineering components and designs and minimizes assembly issues.
- Manufacturing Process Manufacturing of BIS Certification for wrought aluminum Alloy sheets and strips by rolling, annealing, and tempering is a high-technology production process. Those processes also improve mechanical properties while enhancing material surface finish and uniformity. These manufacturing steps are in line with the quality standards to be complied with under IS 737:2008.
- Tests and Quality Control:
Every manufacturer who wants to comply with IS-737:2008 requirements must conduct extended tests including:
- Chemical analyses: That is, the compositions are within specified limits.
- Mechanical tests such as tensile strength, elongation, and hardness.
- Dimensional checks: Conformance to specified tolerances.

Step-by-Step Process of Aluminum Alloy Sheet Manufacturing
- Melting the Metal
Pure aluminum melts in the furnace. At this time other metals such as copper, magnesium, silicon, or zinc are added to produce the alloy required. - Cleaning the Melt
The molten alloy is cleaned to eliminate numerous gases and impurities to provide a clean, smooth structure in the final sheet form. - Casting into Slabs
The liquid alloy is poured into large molds (called slabs or ingots). These solid blocks are the starting point for making sheets. - Preheating the Slabs
The slabs are heated in a furnace to make them soft and uniform, so they can be rolled easily. - Hot Rolling
The hot slabs are passed through heavy rollers that squeeze them into thick sheets or coils while still hot. - Cold Rolling
After they are cooled to room temperature, the sheets are once again rolled at room temperature to the final thickness, strength, and smooth surface finish. - Heat treatment (if required)
Some alloys undergo heat treatment to improve strength, while others are simply hardened by rolling -this step is dependent on the type of alloy. - Surface Finishing
The sheets can be anodized, coated or polished to improve corrosion resistance as well as aesthetics. - Quality Testing
Every batch is tested to evaluate chemical composition, strength, thickness, and dimensions to ensure compliance with BIS standard IS 737:2008. - Cutting and Packaging
Finally, the sheets are cut into required sizes, leveled, packed, and sent to industries for use.
Applications of BIS Certification For Wrought Aluminum Sheets and Strips
