Bill Baldwin -- Baldwin Anthony -- Analyst When we see the price of aluminum in relation the price of copper become more favorable for aluminum, does that show up in your demand for aluminum fairly quickly or not at all or over a period of time? Daniel Jones -- Chairman, President and Chief Executive Officer Well that's been debated over time. We prefer Encore Wire consistently and will continually prefer to ship and sell copper. That's just the way it is. The aluminum piece of that that you're referring to is a substitution depending on the relationship between the cost of each. Normally if aluminum is more expensive so is copper and vice versa. When copper gets to a certain dollar amount, there's no question that in the conversation the substitution question comes up. There are other costs involved with that most of the time. It's not a new scenario, but it doesn't necessarily increase the demand for aluminum beyond what the increase in the demand of copper would be. But it does enter into the conversation in the quote stage pretty early on when copper gets really expensive about what would it take to substitute aluminum for this piece of copper. And so in that, it's definitely in the conversation.
