To Whom it may concern:  We are an American dart manufacturer and we are using 90/10 tungsten nickel-iron alloy rods to make throwing darts.  As our demand for more tungsten billets increases we are looking for suppliers who can provide us with tungsten.  We have been in business for 30 years and make all of our darts in our Santa Maria California factory.  We currently need to have 0.250" diameter in 1.80" and 2.00" and 2.15" lengths and also 0.281" diameter in 2.15" lengths.  We are looking for someone to supply us with 50,000 to 100,000 pieces of these items.
