Famous 1060 H16 aluminum coil for gutters
When it comes to efficient, durable, and weather-resistant gutters, the choice of material significantly impacts the performance and lifespan of the installation. Among various options, the famous 1060 H16 aluminum coil stands out as a premier material designed specifically for gutter fabrication.
What Makes 1060 H16 Aluminum Coil Ideal for Gutters?
At first glance, choosing the right material for gutters may seem straightforward, but ensuring long-term resilience against environmental factors without compromising formability demands technical insight. The 1060 aluminum coil belongs to the 1xxx series, meaning it is commercially pure aluminum (aluminum content ≥ 99.6%). It is well-loved for excellent corrosion resistance—which is critical for gutters consistently exposed to water—and outstanding formability.
By tempering the alloy to H16—a half-hard condition achieved through controlled strain hardening—the material achieves enhanced mechanical strength while retaining sufficient ductility needed for shaping gutter profiles.
Distinctive Functions and Mechanical Benefits
Corrosion Protection and Sustainability
Corrosion resistance of 1060 aluminum coil is naturally elevated due to the high purity content (over 99.6%). When rainwater, sometimes containing contaminants, continuously flows over the gutter surface, inertness to chemical degradation ensures long-lasting service. Moreover, this purity guarantees:
- Low potential impact on runoff water quality, important for environments relying on rainwater collection.
- Reduced maintenance requirements traditionally linked with rust or oxidative buildup seen in steel options.
Mechanical Properties Meeting Demand
The temper H16 delivers a half-hard condition which balances strength (~90 MPa tensile strength) and workability suited for various gutter shapes, corners, and ties. The essential mechanical nuances:
| Property | Value |
|---|---|
| Tensile Strength | 90 - 110 MPa |
| Yield Strength | Approx. 40 - 60 MPa |
| Elongation (Lengthwise) | Approx. 12% |
| Hardness (Brinell) | ~25 HB |
These specs reveal a material solid enough to handle typical external impacts (like debris or foot traffic) while promoting ease of custom-form production lines.
Technical Parameters & Chemical Composition Table
From an engineering perspective, design engineers rely heavily on trustworthy chemical and mechanical standardization. The international implementation standards include:
- Standard conformity: ASTM B209, EN 485-2 and JIS H4000
- Width range: Typically 1000mm to 1250mm for manufacturing ease.
- Thickness range: 0.2mm to 3.0mm, scalable based on gutter size requirements.
Chemical Composition (% weight):
| Element | 1060 Alloy Content Range |
|---|---|
| Aluminum (Al) | ≥ 99.6 |
| Iron (Fe) | ≤ 0.35 |
| Silicon (Si) | ≤ 0.25 |
| Copper (Cu) | ≤ 0.05 |
| Manganese (Mn) | ≤ 0.03 |
| Magnesium (Mg) | ≤ 0.03 |
| Zinc (Zn) | ≤ 0.05 |
| Titanium (Ti) | ≤ 0.03 |
| Others (each total) | ≤ 0.15 |
Such tight compositional control assures consistent gutter production, smooth finish, and corrosion resisting surfaces.
Applications Beyond Conventional Gutters
Though the primary use resembles traditional rainwater gutters, the outstanding formability and stability of 1060 H16 aluminum coil widen its range of applications including:
- Custom architectural gutters: Curved, faceted, or ornate profiles are achieved without metal cracking.
- Downspouts: Require similar strength and seamless fabricability preventing leakage.
- Roof flashings & trims: Spot repair uses call for corrosion-resistant, lightweight solutions compatible with the primary assembly.
- Rainwater collectors & drainage channels: Specialized handling of runoff water engaged by adjustable widths and thickness specifications.
Given its light weight and easy painting/rusting risistibility after anodizing or coating, installation & maintenance also becomes user/commercialist advantage factors.
Temper and Implementation Standards
“Tempering” in aluminum alloys describes mechanical and heat treatments altering metal properties. The H16 temper for 1060 aluminum coil defines a:
- Half-hard temper
- Specified by specific rolling reductions (~1/8 thickness reduction)
- Aims to improve strength significantly while preventing excessive brittleness
Relevant standards specify compliance to:
- ASTM B209 – Aluminum and aluminum-alloy sheet and plate specification, ensuring mechanical, chemical, and dimensional integrity.
- EN 485-2 – Aluminum and aluminum alloys - Sheet, strip, and plate - Mechanical properties, outlining minimum guaranteed property levels for manufacturing tolerances to curb quality lapses.
