ィラーとして最適であると考えられている。Among these, the method of adding conductive fillers to plastics is seen as promising in terms of cost and shielding performance. Conductive fillers include copper, brass, stainless copper, aluminum, and aluminum alloys.
Among these fillers, aluminum and aluminum alloy fillers have a lower specific gravity than other fillers, so
-Since the specific gravity of the added plastic is also small, it is considered to be optimal as a conductive filler.

性フィラー用アルミニウム合金である。As a result of extensive research into materials, we have discovered an aluminum alloy for conductive fillers that has extremely low volume resistivity of filler-added plastics and an extremely small increase in the volume resistivity due to heating, compared to conventional aluminum and aluminum alloy fillers. That is, in the present invention, zinc is added to 10 to 60
This is an aluminum alloy for conductive filler containing 1% by weight, with the remainder consisting of axes and aluminum.

When a predetermined amount of aluminum alloy filler containing % by weight is added to plastic, a plastic is obtained which has significantly lower volume resistivity than conventional aluminum and aluminum alloy fillers, and whose increase in volume resistivity due to heating is also small. However, the above effects cannot be obtained if the zinc content is less than 10% by weight or exceeds 60% by weight.

It shows.

ことが実証されている。Plastic containing filler made of the alloy of the present invention was heated to 80°C.
When heated for 24 hours, the volume resistivity becomes 1 compared to before heating.
It increases by about 0 times. On the other hand, when plastics to which the comparative alloy In filler was added were heated at 80°C for 24 hours, the volume resistivity increased by about 10 to 104 times compared to before heating, and in the end, the plastics with the filler made from the alloy of the present invention were added. It has been demonstrated that the volume resistivity of the plastic is much lower than that of the plastic with filler made of a comparative alloy.
