I don't know what it is, but a meteorite with a metallic appearance would have more than a barely noticeable attraction to a strong magnet. Metallic material in meteorites is always a mixture of iron and nickel which results in strong attraction. Only low-metal chondrites, carbonaceous chondrites and achondrites have little or no attraction to a magnet, but they don't look like the rock you're showing. There are some terrestrial minerals and many rocks that can have a metal-like appearance plus numerous man-made possibilities that could contain non-ferromagnetic metals.
