Key Features
Al 1050 Aluminum Disk is a commercially pure 1xxx series disk with a minimum aluminum content of 99.5%, offering a defined planar geometry with consistent surface area and thickness for electrochemical, corrosion, and surface science applications:
Electrical & Thermal Conductivity (~57–59% IACS, ~218 W/m·K)
Electrical conductivity of ~57–59% IACS and thermal conductivity of ~218 W/m·K — among the highest available in a commercial-grade aluminum disk — maintained by the low total Fe+Si content that minimises solid-solution electron scattering.
Defined Planar Geometry & Consistent Surface Area
The disk format provides a fixed circular geometry with a planar face and controlled thickness, enabling coupon-to-coupon reproducibility in surface analysis, electrochemical testing, and corrosion studies where sample geometry is an experimental variable.
Naturally Passivating Oxide Layer
The self-limiting Al₂O₃ layer provides a chemically reproducible starting surface for electrochemical measurement and anodization without pre-treatment — consistent across a batch of disks from the same material lot.
High Ductility & Machinability
High ductility supports precision stamping and machining to close dimensional tolerances, enabling custom disk dimensions for non-standard sample holders and electrochemical cell configurations.
Moderate Strength from Fe+Si Content
Small Fe+Si additions relative to higher-purity grades provide marginally improved mechanical strength and work-hardening response, reducing deformation during coupon preparation and handling.
Industrial Applications
Al 1050 Aluminum Disk is used across electrochemistry, corrosion science, surface analysis, and materials research — where the defined disk geometry and consistent 99.5% Al composition provide a reproducible commercial-purity sample platform:
- ✦ Electrochemical Working Electrodes
- Defined surface area enables accurate current density calculation in corrosion studies, anodization kinetics, and inhibitor performance measurements — where coupon-to-coupon geometry consistency is essential for comparable results across a test series.
- ✦ Corrosion Test Coupons
- Used in salt-spray, immersion, and cyclic corrosion testing where alloy composition and disk geometry must be consistent across a test series for statistically comparable results.
- ✦ Anodization Blanks for Functional & Decorative Oxide Coatings
- 1050's surface uniformity and anodization response support standard industrial oxide finishes where batch consistency across a set of disks is required and high-purity grades are not economically justified.
- ✦ Thermal Diffusivity Specimens
- The disk geometry and known alloy specification support direct comparison of thermal properties across conditions in thermal diffusivity and heat capacity measurement studies.
- ✦ Recrystallization & Microstructural Research
- Used as a standard benchmark for 1xxx series microstructural studies examining the effects of cold deformation, annealing, and recrystallization on grain structure and mechanical properties.
