MTC Manufacture Silica Core Material for Casting Structural Aluminium Aerospace Parts

Morgan Advanced Materials manufactures components and sub-assemblies using an extensive range of materials, including structural and piezoelectric ceramics, dielectrics, braze alloys, and specialist coatings.

It works with manufacturers' design and R&D teams at local, national and international level on projects from concept and feasibility studies through prototype development to full production. The business employs some 2,500 people and has 23 manufacturing sites worldwide across Europe, the US, Mexico, China and Australia.

Morgan Advanced Materials (MTC) announced that its Certech manufacturing site in Wilkes-Barre, Pennsylvania produces H7, a high silica core material with a coarse particle size distribution and open pore structure, ideal for use in casting of highly technical aluminum structural parts in aerospace applications.

Compatible with most steel, copper and aluminum alloys, H7 is used most frequently for aluminum castings in which cores cannot be leached out chemically, so core removal is accomplished by water blast or a knockout operation. Aerospace manufacturers are switching to H7 to take advantage of the material's ability to withstand the pressure of wax injection and dewax stress and still remain easy to wash out. Commercial and military applications using H7 include missiles and helicopters, as well as a variety of aircraft body parts, including doors and handles.

"Our unique H7 material is made of fused silica that has high porosity and tightly controlled properties," said Paul Strasser, Sales Manager for MTC Certech PA. "The material's extreme leachability makes it excellent for casting structural parts with small, long passageways, where it performs extremely consistently, permitting 100 percent removal of core material."
