Eyelet Stock

Marudhar upholds international standards in the fabrication of its eyelet stock, a fundamental material extensively utilised in a variety of applications. Through the utilisation of primary ingots and advanced control systems, Marudhar delivers eyelet stock with meticulous gauge tolerances, alongside meeting stringent elongation and length criteria, establishing a product of unparalleled quality and reliability.

Eyelet Strips Stock

Specifications:

Our aluminium eyelet strip stock is used to produce superior-quality eyelets. It comprises two parts - EYELETS RIVET TORUS STOCK and EYELETS RIVET FLAT STOCK. Aluminium eyelets rivet torus stock is soft, of a smooth surface, has no burr and is of high quality. According to the analysis, the chemical composition, cold rolling, shearing, heat treatment processes, intrinsic properties organization, hardness and other mechanical properties of materials will affect the application.

In common, for making the aluminium eyelets rivet torus stock the alloys used are 1050 and 1100 with the temper O which means soft, the thickness is 0.120 – 0.200mm and the width is 12 – 1250mm. While the eyelets rivet flat stock comes with GEQ alloy having tempers range as O, H12, H14, H22 and H24. The thickness is 0.120 - 0.350mm and the width is 18 – 1250mm.
