Premium Tungsten Alloy Fishing Sinkers: Advanced Design & Performance

Tungsten Alloy Fishing Sinkers

These sinkers are crafted from a high‑density tungsten‑based alloy, giving them superior weight, durability, and environmental safety—attributes that have made them a favorite among modern anglers.

Key Advantages

• Exceptional Density – roughly 2.5 times that of iron and twice that of lead, enhancing depth control and casting distance.
• Compact Size – lightweight and easy to handle, allowing more sinkers to be added to a single line.
• Eco‑Friendly – non‑toxic and non‑polluting, replacing traditional lead sinkers without harming aquatic ecosystems.
• High Heat Resistance – melts at ~3422 °C and maintains integrity even in high‑temperature conditions.
• Superior Corrosion Resistance – resists acids, alkalis, and oxidation, extending service life.
• Durable Finish – retains a polished appearance and resists scratching or breaking from impacts.

Types & Sizes

Sinkers come in a variety of shapes—worm, barrel, needle, bullet, drop—and in weights ranging from 1/16 oz to 2.5 oz, providing anglers with precise control over depth and buoyancy.

Manufacturing Process

The production begins with a carefully proportioned mix of tungsten, nickel, and iron powders, dried under vacuum. The blend is heated to 2300 °C in a nitrogen atmosphere, then injected into molds to form blanks. After cooling, the blanks are sintered at 1500 °C under inert gas and cooled again, yielding a robust, high‑quality sinker.
