Ultra-Thin Decorative Formable Aluminum Tubes

Overview

Crafted via cold drawing from 5052-H32/1050-H14 aluminum, these tubes feature wall thickness as low as 0.5mm, customizable surface finishes, and exceptional formability, ideal for decorative trim, consumer electronics, and architectural accents.

Features

Extreme Formability

Cold Drawn Precision: Wall thickness 0.5-2mm, achieving minimum bend radius 1x OD without cracking, ideal for complex curves (e.g., spirals, arcs) in decorative applications.

Material Ductility:

5052-H32 (elongation 20%): Superior bendability for tight-radius turns in automotive interiors.

1050-H14 (purity 99.5% Al): High thermal conductivity (226 W/mK) for heat-sensitive electronic components.

Decorative Surface Finishes

Premium Coatings:

Anodised in 50+ colors (20μm Type II), including metallic and pearlescent effects, passing 500h salt spray test for indoor use.

Brushed/satin finishes (Ra ≤1.6μm) with anti-fingerprint coating (contact angle ≥110°), ideal for high-touch consumer products.

Embossed Patterns: Custom logos and textures (0.3mm depth) via roll embossing, supporting brand differentiation (MOQ 200 meters).

Dimensional & Structural Quality

Tolerance Control: OD tolerance ±0.03mm, wall thickness ±0.02mm (ISO 2768-1 fine class), ensuring seamless fit in precision assemblies (e.g., watch straps, eyeglass frames).

Seamless Construction: Cold-drawn from single billet to eliminate weak points, achieving tensile strength 15% higher than equivalent extruded tubes (ASTM B241 compliant).

Lightweight & Versatile

Weight Efficiency: Density 2.7g/cm³, 50% lighter than copper tubes, reducing material usage in portable electronics and wearable devices.

Functional Integration: Pre-machined holes (Ø1-5mm) and flared ends for easy attachment of beads, connectors, or fasteners (e.g., M2-M5 threads).

Application

Decorative Trim: Furniture edging, cabinet handles, and lighting fixtures in luxury interiors, with anodised finishes matching high-end design themes (Pantone matching service).

Consumer Electronics: Frames for smartphones, tablets, and wearable devices, offering EMI shielding (anodised black, attenuation ≥15dB at 1GHz).

Architectural Accents: Curved mullions, room dividers, and decorative screens in hotels and retail spaces, with formable design enabling unique 3D structures.
