    Aluminum Casting in Practice: A Case Study of Cast Aluminum Fan Blades

    Posted by Jim Smith, Jr. on 2018 Feb 21

     

     

    A major manufacturer of ventilation systems contacted Eagle Aluminum Cast Products, Inc. when demand was growing and they were ready to make a change.

    The customer had already been producing 48” fan blades for agricultural use through green sand casting, but they’d outgrown that method. Demand projections suggested that permanent mold casting would yield lower per-part costs, with the added benefit of greater consistency.

    Years later, EACP still produces fan blades for the customer through the process of permanent mold casting. Demand has increased even more, and product offerings have become more diverse. Read on to learn how EACP handles the design, production and delivery of this cast aluminum fan blade.

    All About Al: Choosing the Right Aluminum Alloy

    Posted by Jim Smith, Jr. on 2018 Jan 10

     

    In manufacturing, aluminum is rarely pure. Instead, manufacturers form alloys that dramatically increase aluminum’s strength and stiffness, while maintaining its other desirable properties. Both professionals and non-professionals often make comparisons between aluminum and steel, because the two metals are both used for such a wide variety of products.

    But comparing aluminum to steel is a bit like comparing apples to oranges: steel is already an alloy, while aluminum is an element. Carbon steel, a basic steel alloy, is composed of iron (Fe) and carbon (C). Pure aluminum, despite its many winning properties, is too soft and not strong enough for most industrial applications. But aluminum alloys can be thirty times stronger than pure aluminum, and regularly exceed steel in strength-to-weight ratios.

    All About Al: Aluminum's Winning Properties

    Posted by Jim Smith, Jr. on 2017 Dec 7

    Recently in our All About Al blog series we discussed aluminum's history and origins. Now we're getting deeper into why aluminum is the perfect material for manufacturing such a wide range of products.

    Aluminum owes its versatility in manufacturing to a unique set of properties. These include:

    • Low melting temperature
    • Excellent malleability
    • Light weight
    • Corrosion resistance

    All About Al: Crash Course in Aluminum History

    Posted by Jim Smith, Jr. on 2017 Nov 14

    Aluminum is the third most common element on our planet. It’s by far the most abundant metal, and it’s also one of the most versatile.

    Aluminum is light, strong, flexible and corrosion resistant. It can also be shaped relatively easily, in both a solid and molten state, and can be stamped to widths thinner than the human hair.

    You’ll find aluminum in everything from buildings to cars, from Pepsi cans to laptops, and from power lines to bullet trains. But where does this one-of-a-kind metal come from, and how did it get to be so widely used?
