Precision Casting Hardware for Marine Accessories Customized Casting Services

Precision casting technology provides superior manufacturing solutions for marine hardware accessories that demand exceptional corrosion resistance and mechanical reliability in harsh marine environments. Our customized casting services specialize in producing high-performance marine components through advanced investment casting processes that ensure dimensional accuracy and long-term durability in saltwater applications.

Material Selection and Marine-Grade Properties

We utilize specialized marine-grade alloys including bronze (C95500/C86300), stainless steel (316/316L), and aluminum bronze (C95400) specifically formulated for marine applications. These materials demonstrate proven performance characteristics:

• Bronze Alloys: Excellent seawater corrosion resistance with tensile strength 620-690 MPa, yield strength 330-380 MPa

• Stainless Steel 316L: Superior chloride resistance with PREN >25, tensile strength 485-515 MPa, pitting resistance equivalent

• Aluminum Bronze: Outstanding erosion-corrosion resistance with 15-20% elongation and hardness 170-210 HB

The material selection process focuses on achieving optimal performance in marine environments, considering factors such as biofouling resistance, cavitation erosion, and stress corrosion cracking prevention.
