Product Description
1. Cobalt alloys have higher melting points than nickel (or iron) alloys, allowing them to absorb stress to a higher absolute temperature.
2. Cobalt alloys give superior hot corrosion resistance to gas turbine atmospheres due to their high chromium content.
3. Cobalt alloys show superior thermal fatigue resistance and weldability over nickel alloys.
---Excellent wear and corrosion resistance even at high temperatures up to 800
SYTOP cobalt base alloys are a range of cobalt-chromium-tungsten alloys with wear, corrosion, and high thermal resistance. It is widely used in oil & gas, machinery, wood cutting, automotive, paper and food processing industry, etc.

Q1: What is the Warranty for our products?
A1: We own a high-precision grading machine to control geometry dimensions and apply ultra-fine grain size substrate coated with high-performance coatings to guarantee the lifetime of our products, which can satisfy every working condition. If any quality problems occur during this period, we will take on the shipping cost and replacement.
Q2: Do you provide free samples?
A2: Yes, usually, we provide free samples for testing under the condition of freight paid by the customer.
Q3: What is your minimum order requirement?
A3: We will indicate the MOQ for each item in the quotation sheet. We accept the sample and trial order. If the quantity of a single item can't reach the MOQ, the price should be the sample price.
Q4: What is the delivery time of your products?
A4: It depends on the inventory availability. If items needed are in stock, the delivery time would be within 8 workdays, but if not the delivery time would be around 20 workdays.
Q5: Can you manufacture Special-shaped products?
