Troutline Tungsten Wire 0.10mm diameter 5m/bag

Product Description

The Troutline Tungsten Wire is an excellent choice for adding discreet, non-toxic weight to small and micro nymphs, Perdigons, and buzzers. In situations where tungsten beads may spook fish or lead wire is too thick, this ultra-fine 0.1mm tungsten wire provides the ideal alternative. With a purity of 99.7%, it offers high density and effective sink rates without compromising the slim silhouette of your flies.

Tungsten wire is especially valuable when tying slim-bodied patterns, where you want to increase weight without bulk—making it perfect for competition-style flies or clear-water presentations. Additionally, it’s lead-free, environmentally safe, and increasingly necessary as many rivers now prohibit the use of lead-based weight.

We recommend using this wire as a substitute for traditional tying thread when building small, heavy-bodied flies. It can significantly increase the weight without affecting the fly’s profile—ideal for Perdigons or other slim nymphs. For example, using this wire on a size #16 hook with a 2.5mm tungsten bead increased the overall fly weight by up to 25%.
