Why Tungsten?
Tungsten generally are refractory metal, which have two phase composites consisting of W-Ni-Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten is added with Co、Mo Cr, etc.
They have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90 to 98weight percent and is the reason for their high density (between 16.5 and 18.75g/cm3). Nickel,iron land copper serve as a binder matrix, which holds the brittle tungsten grains together an which makes the alloys ductile and easy to machine.
Tungsten is about 1.7 times as dense as lead which means that a tungsten sinker is considerably smaller than a lead sinker for the same weight sinker.
With the smaller profile comes a smaller chance of a fish spitting the lure on a bite.The higher density of the tungsten also increases sensitivity so the angler can better feel the bottom structure.
Lead is soft and tends to deform when fishing hard structure which causes lead weights to more easily get caught in rocks where a tungsten weight will not get hung up as often.
The softness of lead also mutes most sounds the weight makes when it hits hard structure. Tungsten will amplify that sound attracting fish.
Lead is a toxic material and an environmental concern. Tungsten is an eco friendly alternative.
