Quick answer: For machined aluminum parts, alloy and temper alone are not enough. Buyers should define the bar diameter, diameter tolerance, straightness over a stated gauge length, surface condition, cut length, inspection method and the amount of machining stock. These requirements determine w...Read more »

Quick answer: Saw cutting is usually the practical choice for straight rectangular aluminum plate blanks, especially when buyers need efficient sizing and machining allowance. Waterjet cutting is better suited to profiles, internal cutouts and near-net shapes without a heat-affected zone. Neithe...Read more »

Specify the rolling direction before sheet is cut into blanks—not after a bend cracks or a part fails inspection. Alloy, temper and thickness remain essential, but orientation is another input that can be lost when sheets are nested, rotated and cut. For buyers of formed aluminum parts, a simple...Read more »

Direct answer: aluminum tube can meet its alloy and wall-thickness requirement yet still cause assembly, sealing or machining problems if ovality and straightness are not defined. Buyers should specify how each characteristic is measured, over what length and against which product standard or dr...Read more »

6061-T6 and 6082-T6 are both heat-treatable Al-Mg-Si extrusion alloys, but they should not be treated as automatic substitutes. In structural profile projects, 6082-T6 is often evaluated when higher mechanical strength is the priority, while 6061-T6 remains a widely used choice for welded, mach...Read more »

A plate that meets incoming flatness requirements can still move after machining. Distortion occurs when material removal, clamping and heat release residual stress unevenly. T651 plate is stress relieved by stretching and is often preferred for machined parts, but the temper designation cannot ...Read more »

EXTRUSION PROCUREMENT GUIDE Aluminum Extrusion Tolerances for Project Buyers A profile can meet its alloy and temper requirement but still create assembly problems if straightness, twist, angularity, wall thickness or cut length is not defined. The drawing and purchase order should identify the...Read more »

How Is Alumina Produced? The Bayer Process from Bauxite to Aluminum Oxide Alumina is the main intermediate material used to produce primary aluminum. It is also known as aluminum oxide, with the chemical formula Al₂O₃. Most metallurgical alumina is produced from bauxite through the Bayer ...Read more »

Who Discovered Aluminum? From Ørsted’s 1825 Discovery to Modern Aluminum Production Aluminum is one of the most widely used industrial metals today, but producing metallic aluminum was once extremely difficult. Although aluminum compounds are abundant in nature, the metal is strongly bound to ot...Read more »
