Quick answer: Bend allowance is the arc length of the neutral axis through a bend. It depends on bend angle, inside radius, sheet thickness and the K-factor used for the actual material, temper, tooling and forming method. A generic aluminum K-factor chart is a starting estimate, not an automati...Read more »

Quick answer: To reduce cracking during aluminum-tube flaring, confirm that the alloy and temper are formable for the required expansion, cut the end square, deburr the ID and OD, remove scratches in the forming zone, use the correct flare geometry and compatible lubrication, form progressively ...Read more »

ALUMINUM FILLER METAL SELECTION ER5183 and ER5356 are not automatic substitutes just because both are aluminum-magnesium filler metals. When the base material is 5083 aluminum, the approved welding procedure, required joint properties, service environment, filler classification and delivery for...Read more »

ALUMINUM FILLER METAL ORDERING ER4043 identifies the filler alloy. MIG wire and TIG rod describe how that filler is supplied and used. Before ordering, confirm the welding process, filler classification, diameter, package form, equipment compatibility, quantity and required documentation. A req...Read more »

Aluminum foil pinholes are small through-openings that allow light to pass through plain foil. They matter because a foil layer is often selected for barrier performance, printing, lamination, insulation or electrical use. A buyer should not rely on the word “pinhole-free” alone. The purchase s...Read more »

How to Specify Drilled Holes in Aluminum Sheet and Plate A drilled hole is not defined by diameter alone. Aluminum alloy and temper, material thickness, tool condition, work support, feed, chip evacuation and the required edge condition all affect the finished hole. A useful drawing or RFQ shoul...Read more »

1050 aluminum plate can be considered for busbar and electrical conductor components because it belongs to the commercially pure aluminum series. However, an alloy name alone does not determine current rating. A useful specification must connect conductivity, section size, temperature rise, temp...Read more »

A 6061-T6 aluminum tubing size chart can tell a buyer what dimensions are commonly listed, but it cannot decide the correct wall thickness for a real component. The useful decision begins with outside dimensions, inside clearance, load mode, manufacturing route and the standard named on the purc...Read more »

Do Not Order Five-Bar Plate by “3 mm” Alone Aluminum tread plate thickness can mean either the smooth base thickness or the overall thickness measured to the top of the raised pattern. Those values are not interchangeable. If a drawing, quotation or purchase order says only “3 mm checker plate,”...Read more »

Alclad vs Bare Aluminum: What Buyers Need to Know Alclad aluminum combines a high-strength aluminum-alloy core with thin, corrosion-resistant aluminum-alloy surface layers that are metallurgically bonded during rolling. Bare aluminum sheet has no separate cladding layer: the exposed surface is t...Read more »
