Nimonic 75, 80A, 90 - Customizable cutting of sheet metal

Nimonic 75, 80A, 90 - Customizable cutting of sheet metal
Nimonic 75, 80A, and 90 alloy sheets are high-performance nickel-chromium-based superalloy sheets renowned for their exceptional strength, creep resistance, and excellent oxidation resistance at high temperatures (Nimonic 75 up to 1000°C). Specialized suppliers offer custom cutting services for these alloys, including precision laser cutting, waterjet cutting, and shearing, to meet the specific needs of industries such as aerospace and turbine manufacturing.
What is NIMONIC 75 material?
NIMONIC 75 alloy is an 80/20 nickel-chromium alloy with added titanium and carbon. This alloy was originally introduced in the 1940s for the manufacture of turbine blades. It is easy to machine and weld, and possesses good corrosion resistance, mechanical properties, and heat resistance.

FAQ
Q1: Can I mix different grades (e.g., 75 and 80A) in a single shipment?
A: Absolutely. We specialize in consolidated shipping. By sourcing all your Nimonic requirements from a single China factory, you reduce logistical complexity and save on total freight costs to Europe, India, or the Middle East.
Q2: Why does Nimonic 90 cost more than Nimonic 75?
A: Nimonic 90 contains roughly 15-21% Cobalt (Co), which is an expensive strategic metal. The Cobalt significantly enhances the alloy's strength at temperatures above 800°C, making it a "premium" grade compared to the solid-solution Nimonic 75.
Q3: How do you handle express shipping for urgent MRO needs?
A: We have strategic partnerships with DHL, FedEx, and major air-freight carriers. For inventory in stock, we can dispatch within 48 hours, reaching major global hubs in 5-7 business days.
