LFT-G® PA6 LGF50-NG05 | The Ultimate Metal Replacement PA6 GF50
LFT-G® 50% Long glass fiber nylon6 (PA6)
When engineers specify PA6 GF50, they are pushing plastics to their absolute limit, usually to replace metal. However, standard short-fiber PA6 GF50 suffers from a fatal flaw: it is extremely brittle. LFT-G® PA6-LGF50-NG05 is the structural evolution that solves this.
This Natural Grade (NG05) composite packs a massive 50% Long Glass Fiber reinforcement into a tough Polyamide 6 matrix. The long fiber network creates an internal skeleton that provides the stiffness of die-cast aluminum but with significantly higher impact resistance and fatigue life than short-fiber equivalents. It is the ultimate choice for parts that must bear heavy static loads, resist high temperatures, and never fail.
√ Rivaling Metal Stiffness: With a flexural modulus exceeding 15,000 MPa, it offers a true alternative to zinc and aluminum castings.
√ Eliminates "Short Fiber Brittleness": The entangled long fibers arrest crack propagation, allowing the part to absorb shock loads that would shatter standard PA6 GF50.
√ Superior Creep Resistance: Maintains tight dimensional tolerances under immense loads and heat (up to 160°C), essential for precision mechanical parts.

Case Study: Heavy-Duty Truck Mirror Arm
Engineering Challenge
A commercial truck OEM needed to replace a heavy die-cast aluminum mirror arm. The part must extend far out from the cab, support a heavy mirror head, and have **zero vibration** at highway speeds to ensure driver visibility. Standard PA6 GF50 was too flexible, causing "mirror shake."
LFT Solution & Result
LFT-G® PA6-LGF50 was the only plastic rigid enough to dampen the vibrations. The long-fiber structure provided the necessary modulus (stiffness) to hold the mirror steady. The result was a **45% weight reduction**, improved aerodynamics, and total elimination of corrosion issues common with aluminum arms.
Performance Pillars: High-Load Applications
🏹
Archery Bow Limbs
Requires immense stored energy and fatigue resistance. LFT PA6 LGF50 offers the high modulus to store power and the toughness to release it thousands of times without snapping.
🛠
Construction Anchors
Safety-critical expansion anchors. Replaces steel. The high shear strength and creep resistance ensure the anchor holds its grip in concrete under constant tension over decades.
🚗
High-Pressure Pump Bodies
For industrial pressure washers. The 50% LGF content provides burst strength rivaling aluminum, while the Nylon 6 base offers resistance to oils and heat generated by the pump.
People Also Ask (Google PAA)
1. Is Nylon 6 (PA6) stronger than aluminum?
A: By weight, yes. While aluminum has a higher absolute stiffness, LFT-G® **PA6 LGF50** has a superior *specific strength*. It allows you to design parts that are equally strong but 40-50% lighter than their aluminum counterparts, with the added benefits of corrosion resistance and sound damping.
2. What are the disadvantages of 50% glass fiber Nylon?
A: The main challenge with *short fiber* PA6 GF50 is extreme brittleness and poor surface finish (floating fibers). **LFT-G® Long Fiber** technology solves this. The long fiber network significantly improves impact toughness compared to short fibers, and our specialized processing ensures a resin-rich surface for a better finish.
3. How does moisture affect 50% glass filled Nylon?
A: Nylon naturally absorbs moisture, which lowers stiffness but increases toughness. However, with **50% glass reinforcement**, this effect is minimized. The dense glass skeleton dominates the mechanical properties, ensuring the part remains rigid and dimensionally stable even in humid environments, unlike unfilled or low-glass nylons.
