Definition of Aluminum 6082 | 3.2315 | 64430| AlSi1MgMn
Aluminum 6082 | 3.2315 | 64430 | AlSi1MgMn is a strong, lightweight aluminum alloy made mainly with magnesium, silicon, and manganese. It offers good corrosion resistance, weldability, and machining performance. Aluminum 6082 is often used when parts need more strength than many common 6000-series aluminum grades. Typical uses include structural parts, machine components, frames, automotive parts, brackets, and precision CNC-machined products.

Why Aluminum 6082 | 3.2315 | 64430| AlSi1MgMn Matters in CNC Workshops
- Good machinability: Aluminum 6082 works well with CNC milling, turning, drilling, and cutting for accurate custom parts.
- High strength: It provides good strength for structural and mechanical components while remaining much lighter than steel.
- Excellent corrosion resistance: Aluminum 6082 performs well in many outdoor, industrial, transportation, and general engineering environments.
- Good for finishing and welding: It can be welded and also responds well to anodizing, giving workshops more options after machining.
Surface Finishes forAluminum 6082 | 3.2315 | 64430| AlSi1MgMn
As-Machined
The default finish from CNC machining plastic stock (Delrin, nylon, HDPE, ABS). Visible linear tool path scallop marks across machined surfaces with a matte plastic sheen. No secondary operation suitable for functional components, jigs, fixtures, and internal parts where cosmetic appearance is secondary to dimensional accuracy.
Flame Polished
Quick post-fabrication process that passes a controlled flame over acrylic (PMMA) cut edges, melting the surface micro-layer to produce a crystal-clear, glossy, transparent edge. Fast and cost-effective for acrylic sheet edges produces optical clarity on cut borders without the labor of hand polishing. Ideal for display cases, signage, and acrylic enclosures.
Vapor Polished
Post-fabrication chemical process that exposes transparent plastic parts (acrylic, PC, PETG) to solvent vapor, melting and smoothing the surface micro-layer to dramatically improve optical clarity and gloss. Removes machining lines and produces crystal-clear transparent parts — essential for prototype lenses, light guides, display windows, fluidic chambers, and medical components requiring optical transparency.
Painted
Post-fabrication spray painting in any custom color (matte, satin, gloss, metallic) followed by screen printing or pad printing for logos, labels, buttons, and graphics. Applied over a primed plastic surface for uniform color and adhesion. Allows custom fabricated plastic parts to match production aesthetics widely used for control panels, instrument faces, enclosures, and marketing/showcase components requiring exact brand color and graphic printing.
Sanded
Post-fabrication sanding with progressively finer grit sandpaper (typically 240–600 grit) produces a uniform low-gloss matte non-reflective surface. Hides machining marks, scratches, and surface inconsistencies while providing a soft tactile feel. Used for HDPE, UHMW, and nylon components where a durable, non-glare, fingerprint-resistant matte appearance is desired for industrial and functional parts.
Heat Formed
Thermoforming process that heats plastic sheet (acrylic, polycarbonate, ABS) to its glass transition temperature and bends it over a form tool to create precise angles and curved shapes. Produces clean, smooth bend radii with consistent surface finish no tool marks at the bend. Used for display stands, guards, enclosures, signage, and custom fabricated parts requiring 3D formed shapes from flat sheet stock.
