Key Features
Iron Disc is a precision-cut circular component available across a comprehensive range of variations, allowing customization for strength, hardness, corrosion resistance, and other properties to match specific design requirements:
Well-Characterized Mechanical Baseline (Tensile Strength 180–210 MPa, Yield Strength 120–150 MPa)
With a body-centered cubic structure, tensile strength of 180–210 MPa, and yield strength of 120–150 MPa, Iron Disc provides the well-characterized mechanical baseline that underpins much of modern materials engineering — a reference point for comparative studies and component design across structural and mechanical applications.
High Melting Point (1535 °C) & Thermal Conductivity (80.4 W/m·K)
A melting point of 1535 °C and thermal conductivity of 80.4 W/m·K support Iron Disc's use across a wide span of thermal and structural applications, where iron's well-documented thermal behavior provides predictable performance in both industrial component design and research-grade thermal characterization work.
Customizable Across a Comprehensive Range of Property Variations
The comprehensive range of variations available allows customization for strength, hardness, corrosion resistance, and other properties to match specific design requirements — giving engineers the ability to select the optimum grade and configuration for applications spanning automotive components to industrial equipment.
Density of 7.87 g/cm³ Supporting Predictable Structural Performance
A density of 7.87 g/cm³, combined with iron's well-characterized mechanical properties, provides the predictable structural performance baseline required across automotive components, construction materials, industrial equipment, and consumer products where consistent, well-documented material behavior is essential for reliable design.
Standardized Specimen for Corrosion, Magnetic & Mechanical Behavior Research
In research, Iron Disc serves as a standardized specimen for corrosion testing, magnetic property characterization, and mechanical behavior studies where a well-documented reference metal is required — providing a consistent circular geometry for systematic and comparable experimental programs.
Industrial Applications
Iron Disc is used across automotive, construction, industrial equipment, and consumer product manufacturing, as well as materials research, wherever a precision circular component with well-characterized and customizable properties is required:
- ✦ Automotive Component Manufacturing
- Used in automotive component manufacturing, where Iron Disc's customizable strength, hardness, and corrosion resistance allow engineers to select the optimum grade for specific automotive design requirements, from structural components to wear-resistant parts.
- ✦ Construction Materials
- Applied in construction materials applications, where the comprehensive range of available property variations supports selection of iron disc grades matched to specific structural, load-bearing, or corrosion-resistance requirements across building and infrastructure projects.
- ✦ Industrial Equipment & Consumer Product Manufacturing
- Used in industrial equipment and consumer product manufacturing, where Iron Disc's well-characterized mechanical baseline of 180–210 MPa tensile strength provides predictable performance across the wide range of applications spanning these two manufacturing sectors.
- ✦ Thermal & Structural Application Component Design
- Used across thermal and structural application component design, where a melting point of 1535 °C and thermal conductivity of 80.4 W/m·K provide the well-documented thermal performance baseline required for components operating across demanding temperature and structural load conditions.
- ✦ Corrosion Testing, Magnetic Characterization & Mechanical Behavior Research
- Used in research as standardized specimens for corrosion testing, magnetic property characterization, and mechanical behavior studies where a well-documented reference metal is required — providing a consistent, comparable circular geometry for systematic materials science investigations.
