NOVELTY - Soluble aluminum alloy comprises 1-2.3 wt.% gallium, 1.6-3.5 wt.%tin, 0.3-2.5 wt.% lead, 0.9-1.1 wt.% copper, 0.1-0.8 wt.% Titanium, 0.3-1.3 wt.% yttrium, 0.3-2 wt.% silicon, 0.016-0.8 wt.% nickel, 1-1.5 wt.% tungsten carbide, 1-3 wt.% fiber-shaped graphene, 1-1.5% plated lanthanum oxide-copper modified basalt fiber, and aluminum (balance). USE - The soluble aluminum alloy is useful for preparing petroleum underground fracturing tool (claimed) and nderground restrictor component. Can be used underground tool in the fracturing technology in oil-gas field development field e.g. temporary plugging tool and fracturing ball. ADVANTAGE - The soluble aluminum alloy has high plasticity, controllable strength, good dissolution rate, low cost of raw materials, simple operation, easy industrial scale production, and can meet the performance requirements required for the work of a salvaging restricting work. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of soluble aluminum alloy for underground restrictor component.
