Hearst Mining building clad in stone on the left, with extension on the right covered in shot peened aluminum alloy. Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals and composites.
Pusing emerged as a prominent player during the tin mining boom that engulfed Perak in the late 19th and early 20th centuries. The discovery of substantial tin deposits in the Kinta Valley attracted a diverse influx of immigrants, particularly from China, who sought their fortunes in the lucrative mining trade.
