Aluminum Extrusion for Wearable Devices

Wearable devices—smartwatches, fitness trackers, hearables, and medical monitoring wearables—impose some of the most demanding material and manufacturing requirements in the consumer products sector. Structural components must be simultaneously lightweight, strong enough to withstand impact and fatigue in active-use conditions, corrosion-resistant against perspiration and environmental exposure, and dimensionally precise enough to support premium fit and finish.

Our wearable device extrusion solutions are primarily based on 6013 and 7N03 alloys, which offer significantly higher strength than standard 6063 while maintaining processability suitable for the small, complex cross-sections typical of wearable housings and bands. Tensile strength ≥350 MPa and yield strength ≥250 MPa are achievable, meeting the structural requirements for load-bearing frames in smartwatch cases and activity monitor housings.

Biocompatibility and skin-contact safety are addressed through appropriate anodizing and coating specifications, ensuring that surface treatments remain stable under long-term skin contact conditions. For products incorporating wireless communication, our engineering team assists in profile geometry optimization to minimize interference with antenna performance. Thermal management within compact wearable enclosures is also addressed through profile design that facilitates passive heat dissipation.

We support miniaturized profile cross-sections with wall thicknesses as low as 0.6 mm and tolerances to ISO 286 precision grades. Sampling and production timelines are aligned with the rapid iteration cycles typical of wearable product development.

Core Requirement

Technical Implementation

Value Delivered / Application

Primary materials are grades 6013/7NO3, paired with composite engineering plastic structural components; suited to high-end applications such as consumer electronics, smart wearables, and portable smart devices

6013 aviation-grade aluminum alloy forms the main structure, with 7NO3-series modified engineering plastic as auxiliary functional structural components; an integrated molding process achieves a reliable metal-plastic bond

Combines the high strength and rigidity of metal with the light weight, high toughness, and signal transparency of engineering plastic, providing structural and functional support across all use scenarios

Aluminum alloy tensile strength ≥350 MPa; yield strength ≥250 MPa; engineering plastic impact strength ≥50 kJ/m²; structural rigidity withstands a 1.5 m free-fall drop without plastic deformation

6013/7NO3 grade aluminum alloy achieves high strength through precise heat treatment; the engineering plastic uses a toughness-modified formulation, combined with reinforcing rib design to distribute loads and improve overall impact and deformation resistance

Ensures structural integrity of the device during daily use, drops, and impacts, preventing housing cracking or deformation, and significantly improving device lifespan and reliability

Main structure waterproof rating ≥IP68; dustproof rating at the highest level, fully preventing dust ingress; suited to daily waterproofing, swimming, and shallow-water diving scenarios

An integrated sealing structure design, combined with waterproof gaskets and nano waterproof coating; the high-precision assembled 6013 aluminum alloy housing and seamlessly fitted engineering plastic components achieve full-body sealed protection

Effectively blocks the ingress of water, dust, sweat, and other media into the device, protecting core components, adapting to complex use environments, and significantly improving environmental adaptability

Structural components free of sharp edges or burrs, edge fillet radius ≥0.5 mm; material releases no hazardous substances and meets biocompatibility standards; wearing fit conforms to ergonomic design

The 6013 aluminum alloy housing undergoes precision CNC engraving plus edge rounding/passivation; the 7NO3 engineering plastic uses a skin-friendly modified formulation that is non-irritating and non-sensitizing, with structural design conforming to the body’s wearing contours

Prevents skin abrasion or allergic reactions during wear, improving wearing comfort and safety, suited to smart wearable devices worn against the skin for extended periods

Surface hardness ≥3H, wear rate ≤0.05 mg per 1,000 friction cycles; appearance free of scratches, burrs, color variation, or oxidation defects; resistant to sweat corrosion and temperature cycling

The 6013 aluminum alloy surface uses anodizing plus sandblasting to improve surface hardness and wear resistance; the 7NO3 engineering plastic uses an anti-aging, weather-resistant modified formulation with a fine matte/glossy surface finish that resists fingerprints and scratches

Maintains freedom from scratches, discoloration, oxidation, and aging over long-term use, preserving device appearance and texture, and enhancing the premium feel and user experience

Non-signal-area aluminum alloy shielding effectiveness ≥60 dB; signal-area engineering plastic wave transmittance ≥90%; overall device heat dissipation ≥5 W, thermal resistance ≤0.2°C/W

The 6013 aluminum alloy housing uses a zoned design, with signal windows made of high-wave-transmittance 7NO3 engineering plastic to avoid metal shielding of signals; built-in cooling channels combined with high-thermal-conductivity materials achieve rapid heat dissipation from core components

Ensures stable transmission and reception of Bluetooth, WiFi, cellular, and other wireless signals, while rapidly dissipating heat from core components to prevent device throttling or lag, ensuring stable operation

Complies with RoHS and REACH environmental regulations; recyclability ≥90%; no release of hazardous substances; meets domestic and international consumer electronics environmental standards

6013 aluminum alloy is a recyclable metal material; the 7NO3 engineering plastic uses a halogen-free, low-VOC environmentally friendly formulation; the production process releases no heavy metals or hazardous volatiles, meeting environmental compliance requirements throughout its lifecycle

Meets environmental access requirements for domestic and international markets, reducing product compliance risk while aligning with green manufacturing and sustainable development trends
