Abstract
The present invention provides an improved compositional material for a low melting point metal casting equipment and a method for producing the same, wherein said composition does not cause large cracks during operation even if there is a reduction in its physical strength resulting from the non-use of reinforcing asbestos fiber. This material actually has a durability equivalent to/or greater than that of products reinforced with asbestos fiber.
